أَخْبَرَنَا أَبُو صَالِحِ بْنُ أَبِي طَاهِرٍ الْعَنْبَرِيُّ أنبأ جَدِّي يَحْيَى بْنُ مَنْصُورٍ ثنا أَحْمَدُ بْنُ سَلَمَةَ ثنا مُحَمَّدُ بْنُ الْعَلَاءِ أَبُو كُرَيْبٍ الْهَمْدَانِيُّ ثنا أَبُو أُسَامَةَ عَنْ عُبَيْدِ اللهِ بْنِ عُمَرَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ رَسُولَ اللهِ ﷺ صَلَّى فَسَهَا فَسَلَّمَ فِي ��لرَّكْعَتَيْنِ فَقَالَ لَهُ رَجُلٌ يُقَالُ لَهُ ذُو الْيَدَيْنِ يَا رَسُولَ اللهِ أَقَصُرَتِ الصَّلَاةُ أَمْ نَسِيتَ؟ قَالَ مَا قَصُرَتِ الصَّلَاةُ وَمَا نَسِيتُ قَالَ فَإِنَّكَ صَلَّيْتَ رَكْعَتَيْنِ فَقَالَ أَكَمَا قَالَ ذُو الْيَدَيْنِ؟ قَالُوا نَعَمْ قَالَ فَتَقَدَّمَ فَصَلَّى رَكْعَتَيْنِ ثُمَّ سَلَّمَ ثُمَّ سَجَدَ سَجْدَتَيِ السَّهْوِ تَفَرَّدَ بِهِ أَبُو أُسَامَةَ حَمَّادُ بْنُ أُسَامَةَ وَهُوَ مِنَ الثِّقَاتِ
English Translation
Abu Salih ibn Abi Tahir al-Anbari informed us... from Ibn Umar that the Messenger of Allah (peace be upon him) prayed and made an error, giving the salutation after two rak'ahs. A man called Dhul-Yadayn said to him: O Messenger of Allah, has the prayer been shortened or did you forget? He said: The prayer has not been shortened and I did not forget. He said: But you prayed two rak'ahs. He said: Is what Dhul-Yadayn said correct? They said: Yes. So he went forward and prayed two rak'ahs, then gave the salutation, then performed two prostrations of forgetfulness. Abu Usamah Hammad ibn Usamah narrated this exclusively, and he is among the trustworthy narrators.
