Mistake in Sujud (prostrations)

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from Muhammad ibn Sinan from ibn Muskan from abu Basir from who has said the following: “I once asked abu ’Abd Allah عليه السلام, about a man who doubts and does not know if he has performed one or two Sajdah (prostrations). He (the Imam) said, ‘He performs Sajdah (prostration) to ascertain that it is two Sajdah (prostrations).”’

3. It is a narration from him (narrator of previous Hadith) by Ahmad ibn Muhammad from Ahmad ibn Muhammad ibn abu Nasr and Ali ibn Muhammad from Sahl ibn Ziyad from Ahmad ibn Muhammad ibn abu Nasr who has said the following: “I once asked abu al-Hassan عليه السلام, about a man who performs one Rak’at of Salah (prayer), then he remembers in the second Rak’at in Ruku’ (bowing down on one’s knees) position that he has omitted one Sajdah (prostration) of the first Rak’at. He said, ‘Abu al-Hassan عليه السلام, would say that if you omit Sajdah (prostration) in the first Rak’at and do not know if it is one or two; perform Salah (prayer) again until it is correct to say that two Sajdah (prostrations) are performed.’”

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 عليه السلام, has said, ‘He performs one more Sajdah (prostration).”’
