Sahih Muslim Hadith 1272 – As-Sahw

English

[1272] 88 – (571) It was narrated that Abü Weed Al- IShudrI said: "The Messenger of Allah said: 'If one of you is unsure when in prayer and does not know how many (Rak'ah) he has prayed, whether it is three or four, let him ignore what is uncertain and proceed on the basis of what is certain. Then let him prostrate twice before saying the TaslIm. Then if he has prayed five (Rak'ah), that will make his prayer even, and if he has prayed it properly with four, it will annoy the Shaitân."
