أَخْبَرَنَا هَارُونُ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا حَجَّاجٌ، وَرَوْحٌ، - هُوَ ابْنُ عُبَادَةَ - عَنِ ابْنِ جُرَيْجٍ، قَالَ أَخْبَرَنِي عَبْدُ اللَّهِ بْنُ مُسَافِعٍ، أَنَّ مُصْعَبَ بْنَ شَيْبَةَ، أَخْبَرَهُ عَنْ عُتْبَةَ بْنِ مُحَمَّدِ بْنِ الْحَارِثِ، عَنْ عَبْدِ اللَّهِ بْنِ جَعْفَرٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ شَكَّ فِي صَلاَتِهِ فَلْيَسْجُدْ سَجْدَتَيْنِ " . قَالَ حَجَّاجٌ " بَعْدَ مَا يُسَلِّمُ " . وَقَالَ رَوْحٌ " وَهُوَ جَالِسٌ " .
Harun ibn ‘Abd Allah reported to us; he said: Hajjaj and Rawh—namely, Ibn ‘Ubadah—reported to us, from Ibn Jurayj, who said: ‘Abd Allah ibn Musafi‘ informed me that Mus‘ab ibn Shaybah informed him, from ‘Utbah ibn Muhammad ibn al-Harith, from ‘Abd Allah ibn Ja‘far, that the Messenger of Allah (ﷺ) said: “Whoever is uncertain during his prayer, let him prostrate twice.” Hajjaj added: “After he has said the taslim.” Rawh added: “While seated.”
