أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ سُفْيَانَ، قَالَ حَدَّثَنِي أَبُو بَكْرِ بْنُ أَبِي الْجَهْمِ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى بِذِي قَرَدٍ وَصَفَّ النَّاسُ خَلْفَهُ صَفَّيْنِ صَفًّا خَلْفَهُ وَصَفًّا مُوَازِيَ الْعَدُوِّ فَصَلَّى بِالَّذِينَ خَلْفَهُ رَكْعَةً ثُمَّ انْصَرَفَ هَؤُلاَءِ إِلَى مَكَانِ هَؤُلاَءِ وَجَاءَ أُولَئِكَ فَصَلَّى بِهِمْ رَكْعَةً وَلَمْ يَقْضُوا .
It was narrated from Ibn 'Abbas that: The Messenger of Allah (PBUH) prayed at Dhi Qarad and the people formed two rows behind him, one row behind him and one row facing the enemy. He led those who were behind him in praying one rak'ah, then they went and took the place of the others, and the others came and he led them in praying one rak'ah, and they did not make it up.
