Sunan an-Nasa'i 1544

Al-‘Abbas ibn ‘Abd al-‘Azim narrated to us; he said: ‘Abd al-Samad ibn ‘Abd al-Warith narrated to me; he said: Sa‘id ibn ‘Ubayd al-Huna’i narrated to me; he said: ‘Abdullah ibn Shaqiq narrated to us; he said: Abu Hurayrah narrated to us, who said: The Messenger of Allah (peace and blessings be upon him) was encamped between Dajnan and ‘Usfan, besieging the polytheists. The polytheists said, “These people have a prayer they love more than their sons and virgins. Agree on your plan, then attack them all at once.” Jibril (peace be upon him) came and instructed him to divide his Companions into two groups. He was to lead one group in prayer while the other faced the enemy, on guard and carrying their weapons. He would lead them in one rak‘ah; then the first group would fall back and the others advance, and he would lead them in one rak‘ah. Thus, each group would have one rak‘ah with the Prophet (peace and blessings be upon him), while the Prophet (peace and blessings be upon him) would have prayed two rak‘ahs.
