When to perform the Prostration of Forgetfulness

Question :

If a person prays and forgets how many Rak'ahs he has prayed, what should he do?

Answer:

He must base his assumption on what he is sure of, which is the lesser amount and then complete his prayer, then prostrate twice before making the Taslim, according the Hadith of the Prophet in which he said:
"If any of you is in doubt regarding his prayer, and he does not know how much he has prayed, three or four (Rak'ahs), then let him cast aside doubt and base his estimation upon what he is sure of. Then prostrate twice before making the Taslim; if he has prayed five, his prayer will be an intercessor for him, and if he has completed the prayer correctly, it will be a humiliation for Satan.
And through Allah is attained success.
