Yahya related to me from Malik from Yahya ibn Said from Abd ar- Rahman ibn Hurmuz that Abdullah ibn Buhayna said, "The Messengerof Allah ﷺ prayed dhuhr with us and he stood straight up after two rakas without sitting. When he had finished the prayer, he did two sajdas and then said the taslim after that." Malik said, concerning someone who forgot in his prayer and stood up after he had completed four rakas and recited and then went into ruku and then, when he raised his head from ruku, remembered that he had already completed (his prayer), "He returns to a sitting position and does not do any sajda. If he has already done one sajda I do not think he should do the other. Then when his prayer is finished he does two sajdas from the sitting position after saying the taslim."  

أَنَّهُ قَالَ صَلَّى لَنَا رَسُولُ اللَّهِ ﷺ الظُّهْرَ فَقَامَ فِي اثْنَتَيْنِ وَلَمْ يَجْلِسْ فِيهِمَا فَلَمَّا قَضَى صَلاَتَهُ سَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ بَعْدَ ذَلِكَ  

[Machine] "He informed him that the Messenger of Allah ﷺ stood for two units of Dhuhr prayer without sitting down. After completing his prayer, he prostrated two prostrations and then he gave the salutation."  

أَخْبَرَهُ «أَنَّ رَسُولَ اللَّهِ ﷺ قَامَ فِي ثِنْتَيْنِ مِنَ الظُّهْرِ فَلَمْ يَجْلِسْ فَلَمَّا قَضَى صَلَاتَهُ سَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ بَعْدَ ذَلِكَ»  

[Machine] That the Messenger of Allah ﷺ stood during two of the afternoon prayers without sitting in between. After completing his prayer, he prostrated twice and then gave the final salutation.  

أَنَّ رَسُولَ اللهِ ﷺ قَامَ فِي اثْنَتَيْنِ مِنَ الظُّهْرِ فَلَمْ يَجْلِسْ فِيهَا فَلَمَّا قَضَى صَلَاتَهُ سَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ بَعْدَ ذَلِكَ
