Musannaf Ibn Abi Shaybah

Hazrat Ali (may Allah be pleased with him) says: When in doubt while performing Tawaf and it is not known whether the Tawaf has been completed or not, then complete the number about which there is doubt, because Allah Almighty will not punish for performing extra Tawaf.

It was asked from Hazrat Ata: If a person doubts during Tawaf whether he has performed Tawaf or not, what should he do? He replied: He should perform Tawaf again.

Hazrat Abu Majliz says that during the stoning at Jamarat, I forgot how many stones I had thrown. I asked Hazrat Ibn Umar (may Allah be pleased with them both), but he did not give me any answer. Then Hazrat Ibn al-Hanafiyyah passed by me, so I asked him. He said: O Abdullah! In our view, there is nothing more important than prayer. When any one of us forgets in prayer, he repeats the prayer. Hazrat Abu Majliz says that I informed Hazrat Ibn Umar (may Allah be pleased with them both) of this answer, so he said: Indeed, he is from the Ahl al-Bayt; matters have been explained to them correctly.
