Yahya related to me from Malik from Da'ud ibn al-Husayn that Abu Sufyan, the mawla of Ibn Abi Ahmad, said that he heard Abu Hurayra say, "The Messenger of Allah ﷺ prayed asr and said the taslim after two rakas. Dhu'l-Yadayn stood up and said, 'Has the prayer been shortened, Messenger of Allah, or have you forgotten?' The Messenger of Allah ﷺ stood up and completed what remained of the prayer, and then, remaining sitting after saying the taslim, he made two prostrations."
يَقُولُ صَلَّى رَسُولُ اللَّهِ ﷺ صَلاَةَ الْعَصْرِ فَسَلَّمَ فِي رَكْعَتَيْنِ فَقَامَ ذُو الْيَدَيْنِ فَقَالَ أَقَصُرَتِ الصَّلاَةُ يَا رَسُولَ اللَّهِ أَمْ نَسِيتَ فَقَالَ رَسُولُ اللَّهِ ﷺ كُلُّ ذَلِكَ لَمْ يَكُنْ فَقَالَ قَدْ كَانَ بَعْضُ ذَلِكَ يَا رَسُولَ اللَّهِ فَأَقْبَلَ رَسُولُ اللَّهِ ﷺ عَلَى النَّاسِ فَقَالَ أَصَدَقَ ذُو الْيَدَيْنِ فَقَالُوا نَعَمْ فَقَامَ رَسُولُ اللَّهِ ﷺ فَأَتَمَّ مَا بَقِيَ مِنَ الصَّلاَةِ ثُمَّ سَجَدَ سَجْدَتَيْنِ بَعْدَ التَّسْلِيمِ وَهُوَ جَالِسٌ
