On the day of Al-Khandaq (battle of the Trench' the medial arm vein of Sa`d bin Mu`ad [??] was injured and the Prophet pitched a tent in the mosque to look after him. There was another tent for Banu Ghaffar in the mosque and the blood started flowing from Sa`d's tent to the tent of Bani Ghaffar. They shouted, "O occupants of the tent! What is coming from you to us?" They found that Sa`d' wound was bleeding profusely and Sa`d died in his tent.

Sa`d was wounded on the day of Khandaq (i.e. Trench) when a man from Quraish, called Hibban bin Al-`Araqa hit him (with an arrow). The man was Hibban bin Qais from (the tribe of) Bani Mais bin 'Amir bin Lu'ai who shot an arrow at Sa`d's medial arm vein (or main artery of the arm). The Prophet pitched a tent (for Sa`d) in the Mosque so that he might be near to the Prophet to visit. When the Prophet returned from the (battle) of Al-Khandaq (i.e. Trench) and laid down his arms and took a bath Gabriel came to him while he (i.e. Gabriel) was shaking the dust off his head, and said, "You have laid down the arms?" By Allah, I have not laid them down. Go out to them (to attack them)." The Prophet said, "Where?" Gabriel pointed towards Bani Quraiza. So Allah's Apostle went to them (i.e. Banu Quraiza) (i.e. besieged them). They then surrendered to the Prophet's judgment but he directed them to Sa`d to give his verdict concerning them. Sa`d said, "I give my judgment that their warriors should be killed, their women and children should be taken as captives, and their properties distributed." Narrated Hisham: My father informed me that `Aisha said, "Sa`d said, "O Allah! You know that there is nothing more beloved to me than to fight in Your Cause against those who disbelieved Your Apostle and turned him out (of Mecca). O Allah! I think you have put to an end the fight between us and them (i.e. Quraish infidels). And if there still remains any fight with the Quraish (infidels), then keep me alive till I fight against them for Your Sake. But if you have brought the war to an end, then let this wound burst and cause my death thereby.' So blood gushed from the wound. There was a tent in the Mosque belonging to Banu Ghifar who were surprised by the blood flowing towards them . They said, 'O people of the tent! What is this thing which is coming to us from your side?' Behold! Blood was flowing profusely out of Sa`d's wound. Sa`d then died because of that."

On the day of Al-Khandaq (the battle of trench.) `Umar bin Al-Khattab came cursing the disbelievers of Quraish after the sun had set and said, "O Allah's Apostle I could not offer the `Asr prayer till the sun had set." The Prophet said, "By Allah! I, too, have not prayed." So we turned towards Buthan, and the Prophet performed ablution and we too performed ablution and offered the `Asr prayer after the sun had set, and then he offered the Maghrib prayer.

When it was the day of Al-Ahzab (i.e. the clans) and Allah's Apostle dug the trench, I saw him carrying earth out of the trench till dust made the skin of his `Abdomen out of my sight and he was a hairy man. I heard him reciting the poetic verses composed by Ibn Rawaha while he was carrying the earth, "O Allah! Without You we would not have been guided, nor would we have given in charity, nor would we have prayed. So, (O Allah), please send Sakina (i.e. calmness) upon us and make our feet firm if we meet the enemy, as they have rebelled against us. And if they intend affliction (i.e. want to frighten us, and fight against us) then we would not (flee but withstand them)." The Prophet would then prolong his voice at the last words.

When Allah's Apostle returned on the day (of the battle) of Al-Khandaq (i.e. Trench), he put down his arms and took a bath. Then Gabriel whose head was covered with dust, came to him saying, "You have put down your arms! By Allah, I have not put down my arms yet." Allah's Apostle said, "Where (to go now)?" Gabriel said, "This way," pointing towards the tribe of Bani Quraiza. So Allah's Apostle went out towards them .

That his father said, "When `Umar was stabbed, Suhaib started crying: O my brother! `Umar said, 'Don't you know that the Prophet said: The deceased is tortured for the weeping of the living'?"

When the tribe of Bani Quraiza was ready to accept Sa`d's judgment, Allah's Apostle sent for Sa`d who was near to him. Sa`d came, riding a donkey and when he came near, Allah's Apostle said (to the Ansar), "Stand up for your leader." Then Sa`d came and sat beside Allah's Apostle who said to him. "These people are ready to accept your judgment." Sa`d said, "I give the judgment that their warriors should be killed and their children and women should be taken as prisoners." The Prophet then remarked, "O Sa`d! You have judged amongst them with (or similar to) the judgment of the King Allah."

We were in the company of Allah's Apostle in (the battle of) Al-Khandaq, and he was digging the trench while we were carrying the earth away. He looked at us and said, "O Allah! There is no life worth living except the life of the Hereafter, so (please) forgive the Ansar and the Emigrants."

As regards the following Qur'anic Verse:-- "When they came on you from above and from below you (from east and west of the valley) and when the eyes grew wild and the hearts reached up to the throats....." (33.10) That happened on the day of Al-Khandaq (i.e. Trench).
