Abu Huraira reported God's Messenger as saying, “When one of you stands up to pray the devil comes to him and confuses him so that he does not know how much he has prayed. If any of you has such an experience he should perform two prostrations during the period when he sits.”*
Nafi' said that ‘Abdallah b. ‘Umar passed a man while he was praying and gave him a salutation to which the man uttered some words in reply. ‘Abdallah b. ‘Umar went back to him and said to him, “When one of you is greeted while he is engaged in prayer he must not speak, but give a sign with his hand.”
‘Ata b. Yasar said that Abu Sa'id reported God’s Messenger as saying, “When one of you is in doubt aoout his prayer and does not know how much he has prayed, three or four rak'as, he should subtract what he is doubtful about and base his prayer on what he is sure of, then perform two prostrations before giving the salutation. If he has prayed five rak'as they will make his prayer an even number for him, and if he has prayed exactly four they will be a humbling for the devil.”
Muslim transmitted it, and Malik transmitted it from ‘Ata’ in mursal form. In his version it says, “he will make it an even number by these two prostrations.”
God’s Messenger stood up to pray and we heard him say, “I seek refuge in God from you”, then say, “I curse you with God’s curse,” three times, then he stretched but his hand as though he was taking something. When he finished the prayer we said, “Messenger of God, we heard you say something during the prayer which we have not heard you say before, and we saw you stretch out your hand.” He replied, “God’s enemy Iblis came with a flame of fire to put it in my face, so I said three times, ‘I seek refuge in God from you’. Then I said three times, ‘I curse you with God’s perfect curse', but he did not retreat. Thereafter I meant to seize him. I swear by God that had it not been for the supplication of my brother Solomon, he would have been bound and made an object of sport for the Medina children.”*
* Cf. the tradition from Abu Huraira, p. 202. There it says, “my brother.” Here it is “our brother”, but the plural is often used for the singular.
