٤ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ عَمْرِو بْنِ عُثْمَانَ الْخَزَّازِ عَنِ الْمُفَضَّلِ بْنِ صَالِحٍ عَنْ زَيْدٍ الشَّحَّامِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) فِي رَجُلٍ شُبِّهَ عَلَيْهِ وَلَمْ يَدْرِ وَاحِدَةً سَجَدَ أَمْ ثِنْتَيْنِ قَالَ فَلْيَسْجُدْ أُخْرَى. 
4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Amr ibn ‘Uthman al-Khazzaz from al-Mufaddal ibn Salih from Zayd al-Shahham who has said the following: “About a man who doubts and does not know if he has performed one or two Sajdah (prostrations), abu ‘Abd Allah , has said, ‘He performs one more Sajdah (prostration).”’
