Narrated Thawban Thawban, the freed slave of the Messenger of Allah (peace be upon him) said: While I was standing beside the Messenger of Allah (peace be upon him) one of the rabbis of the Jews came and said: Peace be upon you, O Muhammad. I pushed him back so hard that he nearly fell over. Upon this he said: Why do you push me? I said: Why don't you say: O Messenger of Allah? The Jew said: We call him by the name which he was given by his family. The Messenger of Allah (peace be upon him) said: My name is Muhammad, which is how I was named by my family. The Jew said: I have come to ask you (something). The Messenger of Allah (peace be upon him) said: Will it be of any benefit to you, if I tell you that? He (the Jew) said: I shall lend my ears to it. The Messenger of Allah (peace be upon him) drew a line with the help of the stick that he had with him and then said: Ask (whatever you like). Thereupon the Jew said: Where will the human beings be on the Day when the Earth changes into another earth and the Heavens too (change into other heavens)? The Messenger of Allah (p). said: They will be in darkness beside the bridge. He (the Jew) again said: Who amongst the people will be the first to cross (this bridge)? He said: They would be the poor amongst the refugees. The Jew said: What would constitute their breakfast when they would enter Paradise? He (the Holy Prophet) replied: A caul of fish-liver. He (the Jew) said: What would be their food after this? He (the Holy Prophet) said: a bullock which was fed in the different quarters of Paradise would be slaughtered for them. He (the Jew) said: What would be their drink? He (the Holy Prophet) said: They would be given a drink from the fountain which is named Salsabil. He (the Jew) said: I have come to ask you about something which no one amongst the people on Earth knows except an apostle or one or two men besides him. He (the Holy Prophet) said: Would it benefit you if I tell you that? He (the Jew) said: I would lend my ears to that. He then said: I have come to ask you about the child. He (the Holy Prophet) said: The reproductive substance of a man is white and that of a woman (i.e. ovum central portion) is yellow. When they have sexual intercourse and the male's substance (chromosomes and genes) prevails upon the female's substance (chromosomes and genes), it is the male child that is created by Allah's Decree. When the substance of the female prevails upon the substance contributed by the male, a female child is formed by the Decree of Allah. The Jew said: What you have said is true; verily you are an Apostle. He then turned round and went away. The Messenger of Allah (peace be upon him) said: He asked me about such and such things of which I had no knowledge until Allah gave it to me. (Shahih muslim - 146) Narrated Salamah ibn al-Akwa' It has been reported by Salamah ibn al-Akwa': We fought the Battle of Hawazin with the Messenger of Allah (peace be upon him). (One day) when we were having our breakfast with the Messenger of Allah (peace be upon him), a man came riding a red camel. He made it kneel down, extracted a strip of leather from its girth and tethered the camel with it. Then he began to take food with the people and look (curiously around). We were in a poor condition as some of us were on foot (being without any riding-animals). All of a sudden, he left us hurriedly, came to his camel, untethered it, made it kneel down, mounted it and urged the beast which cantered off. A man on a brown she-camel chased him (taking him for a spy). Salamah (the narrator) said: I followed on foot. I ran on until I was near the thigh of the she-camel. I advanced further until I was near the haunches of the camel. I advanced still further until I caught hold of the nose-string of the camel. I made it kneel down. As soon as it placed its knees on the ground, I drew my sword and struck at the head of the rider who fell down. I brought back the camel, driving it along with the man's baggage and weapons. The Messenger of Allah (peace be upon him) came forward to meet me and the people were with him. He asked: Who has killed the man? The people said: Ibn Akwa'. He said: Everything belonging to the man is for him (Ibn Akwa'). (Shahih muslim - 810) Narrated Salamah ibn al-Akwa' (At last) we reached Medina. The Messenger of Allah (peace be upon him) sent his camels with his slave, Rabah, and I was with him. I (also) went to the pasture with the horse of Talhah along with the camels. When the day dawned, AbdurRahman al-Fazari made a raid and drove away all the camels of the Messenger of Allah (peace be upon him), and killed the man who looked after them. I said: Rabah, ride this horse, take it to Talhah ibn Ubaydullah and inform the Messenger of Allah (peace be upon him) that the polytheists have made away with his camels. Then I stood upon a hillock and turning my face to Medina, shouted thrice: Come to our help! Then I set out in pursuit of the raiders, shooting at them with arrows and chanting a (self-eulogising) verse in the Iambic meter: I am the son of al-Akwa' And today is the day of defeat for the mean. I would overtake a man from them, shoot at him an arrow which, piercing through the saddle, would reach his shoulder, and I would say: Take it, chanting at the same time the verse: And I am the son of al-Akwa' And today is the day of defeat for the mean. By God, I continued shooting at them and hamstringing their animals. Whenever a horseman turned upon me, I would come to a tree and (hid myself) sitting at its base. Then I would shoot at him and hamstring his horse. (At last) they entered a narrow mountain gorge. I ascended that mountain and held them at bay throwing stones at them. I continued to chase them in this way until I got all the camels of the Messenger of Allah (peace be upon him) released and no camel was left with them. They left me; then I followed them shooting at them (continually) until they dropped more than thirty mantles and thirty lances, lightening their burden. On everything they dropped, I put a mark with the help of (a piece of) stone so that the Messenger of Allah (peace be upon him) and his Companions might recognise them (that it was booty left by the enemy). (They went on) until they came to a narrow valley when so and so, son of Badr al-Fazari joined them. They (now), sat down to take their breakfast and I sat on the top of a tapering rock. Al-Fazari said: Who is that fellow I am seeing? They said: This fellow has harassed us. By God, he has not left us since dusk and has been (continually) shooting at us until he has snatched everything from our hands. He said: Four of you should make a dash at him (and kill him). (Accordingly), four of them ascended the mountain coming towards me. When it became possible for me to talk to them, I said: Do you recognise me? They said: No. Who art thou? I said: I am Salamah, son of al-Akwa'. By the Being Who has honoured the countenance of Muhammad (peace be upon him) I can kill any of you I like but none of you will be able to kill me. One of them said: I think (he is right). So they returned. I did not move from my place until I saw the horsemen of the Messenger of Allah (peace be upon him), who came riding through the trees. Lo! the foremost among them was Akhram al-Asadi. Behind him was AbuQatadah al-Ansari and behind him was al-Miqdad bin al-Aswad al-Kindi. I caught hold of the rein of Akhram's horse. (Seeing this), they (the raiders) fled. I said (to Akhram): Akhram, guard yourself against them until Allah's Messenger and his Companions join you. He said: O Salamah, if you believe in Allah and the Day of Judgment and (if) you know that Paradise is a reality and Hell is a reality, you should not stand between me and martyrdom. So I let him go. Akhram and AbdurRahman (Fazari) met in combat. Akhram hamstrung AbdurRahman's horse and the latter struck him with his ance and killed him. AbdurRahman turned about riding Akhram's horse. AbuQatadah, a horseman of the Messenger of Allah (peace be upon him), met AbdurRahman (in combat), smote him with his lance and killed him. By the Being Who honoured the countenance of Muhammad (peace be upon him), I followed them running on my feet (so fast) that I couldn't see behind me the Companions of Muhammad (peace be upon him), nor any dust raised by their horses. (I followed them) until before sunset they reached a valley which had a spring of water, which was called Dhu Qarad, so that they could have a drink, for they were thirsty. They saw me running towards them. I turned them out of the valley before they could drink a drop of its water. They left the valley and ran down a slope. I ran (behind them), overtook a man from them, shot him with an arrow through the shoulder blade and said: Take this. I am the son of al-Akwa'; And today is the day of annihilation for the people who are mean. The fellow (who was wounded) said: May his mother sweep over him! Are you the Akwa' who has been chasing us since morning? I said: Yes, O enemy of thyself, the same Akwa'. They left two horses dead tired on the hillock and I came dragging them along to the Messenger of Allah (peace be upon him). I met Amir who had with him a container having milk diluted with water and a container having water. I performed ablution with the water and drank the milk. (shahih muslim - 828)
