When we wrote the Holy Qur'an, I missed one of the Verses of Surat-al-Ahzab which I used to hear Allah's Messenger (ﷺ) reciting. Then we searched for it and found it with Khuza`ima bin Thabit Al-Ansari. The Verse was:-- 'Among the Believers are men Who have been true to Their Covenant with Allah, Of them, some have fulfilled Their obligations to Allah (i.e. they have been Killed in Allah's Cause), And some of them are (still) waiting" (33.23) So we wrote this in its place in the Qur'an.
Sahih al-Bukhari Book 64, Hadith 95
← Previous Hadith His uncle (Anas bin An-Nadr) was absent from the battle of Badr and he said, "I was absent from the first battle of the Prophet (i.e. Badr battle), and if Allah should let me participate in (a battle) with the Prophet, Allah will see how strongly I will fight." So he encountered the day of Uhud battle. The Muslims fled and he said, "O Allah ! I appeal to You to excuse me for what these people (i.e. the Muslims) have done, and I am clear from what the pagans have done." Then he went forward with his sword and met Sad bin Mu'adh (fleeing), and asked him, "Where are you going, O Sad? I detect a smell of Paradise before Uhud." Then he proceeded on and was martyred. No-body was able to recognize him till his sister recognized him by a mole on his body or by the tips of his fingers. He had over 80 wounds caused by stabbing, striking or shooting with arrows.

Sahih al-Bukhari Book 64, Hadith 94 Next Hadith → When the Prophet (ﷺ) set out for (the battle of) Uhud, some of those who had gone out with him, returned. The companions of the Prophet (ﷺ) were divided into two groups. One group said, "We will fight them (i.e. the enemy)," and the other group said, "We will not fight them." So there came the Divine Revelation:-- '(O Muslims!) Then what is the matter within you that you are divided. Into two parties about the hypocrites? Allah has cast them back (to disbelief) Because of what they have earned.' (4.88) On that, the Prophet (ﷺ) said, "That is Taiba (i.e. the city of Medina) which clears one from one's sins as the fire expels the impurities of silver."
