of the polytheists there was Khalid bin Walid (before converting to Islam). The polytheists said, 'We can seek their carelessness and negligence'. Then came down (verse) about the prayer Khauf -between Zhuhur and Asr, then the Messenger of Allah sallallahu 'alayhi wa sallam performed the Asr prayer by dividing us into two groups. One group prayed with the Messenger of Allah, while the others guarded him. He sallallahu 'alayhi wa sallam recited takbir with the two groups. Then he bowed', then all bowed. 'Alaihi Wa Sallam stood up and bowed' the second with the group behind (who guarded him earlier). Then he prostrated with the group right behind him, and after that they retreated and stood in the position of their friends, while their friends came forward and bowed down. Then he greeted. Thus all of them pray two rak'ahs and two rak'ahs with their imam. And the Prophet sallallaahu 'alaihi wasallam used to pray Khauf once in Bani Sulaim.
