١ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ قَالَ سُئِلَ أَبُو عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنْ رَجُلٍ سَهَا فَلَمْ يَدْرِ سَجْدَةً سَجَدَ أَمْ ثِنْتَيْنِ قَالَ يَسْجُدُ أُخْرَى وَلَيْسَ عَلَيْهِ بَعْدَ انْقِضَاءِ الصَّلاَةِ سَجْدَتَا السَّهْوِ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “Abu ’Abd Allah , was asked about a man who becomes confused and does not know if he has done one or two Sajdah (prostrations). He (the Imam) said, ’He performs another Sajdah (prostration) and after completion of Salah (prayer) two Sajdah (prostration) because of mistake is not necessary.’”
