Sunan Abi Dawud 1019
‘Abd Allah (b. Mas’ud) said :
The Messenger of Allah (ﷺ) prayed five rak’ahs in the noon prayer. He was asked whether the prayer had been extended. He asked what they meant by that. The people said : you prayed five rak’ahs. Then he made two prostrations after having given the salutation.
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، وَمُسْلِمُ بْنُ إِبْرَاهِيمَ، - الْمَعْنَى - قَالَ حَفْصٌ حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ، قَالَ صَلَّى رَسُولُ اللَّهِ صلى الله عليه وسلم الظُّهْرَ خَمْسًا ‏.‏ فَقِيلَ لَهُ أَزِيدَ فِي الصَّلاَةِ قَالَ ‏
"‏ وَمَا ذَاكَ ‏"‏ ‏.‏ قَالَ صَلَّيْتَ خَمْسًا ‏.‏ فَسَجَدَ سَجْدَتَيْنِ بَعْدَ مَا سَلَّمَ ‏.‏
