وَ عَنْهُ عَنْ مُحَمَّدِ بْنِ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ اَلْحُسَيْنِ بْنِ سَعِيدٍ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنِ اِبْنِ مُسْكَانَ عَنْ أَبِي بَصِيرٍ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنْ رَجُلٍ شَكَّ فَلَمْ يَدْرِ سَجَدَ سَجْدَةً أَمْ سَجْدَتَيْنِ قَالَ« يَسْجُدُ حَتَّى يَسْتَيْقِنَ»
And from him, from Muhammad ibn Yahya from Ahmad ibn Muhammad from al-Husayn ibn Sa’id from Muhammad ibn Sinan from Ibn Muskan from Abu Basir, who said:
I asked Abu Abdillah عليه السلام about a man who doubts and does not know whether he has prostrated once or twice. Imam عليه السلام said: "Let him prostrate until he is certain."
