Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "When one of you prays and he does not know whether he has added or subtracted Rak‘ahs to, or from, his prayer, he should perform two prostrations while he is sitting. If the devil comes to him and says: 'You have broken your ablution,' then he should say: 'You have lied,' unless he smells it with his nose or hears it with his ears."
Meaning of the Hadīth: If a person prays and, while doing so, doubts whether his prayer is complete or incomplete or whether he has added to it, what should he do? The Messenger of Allah (may Allah's peace and blessings be upon him) says that in this case, one has to offer two prostrations after he finishes the recitation of the Tashahhud at the end of the prayer. He should do this while he is sitting, and this means that he is not required to stand up in order to perform such prostration. The apparent meaning of this Hadīth is that if the praying person doubts whether he has added or omitted something, then he is only required to perform two prostrations in compliance with the apparent indication. However, this apparent indication contradicts the explicit wording of the Hadīth reported by Abu Sa‘īd (may Allah be pleased with him) and which is narrated in Sahīh Muslim. It reads: "When any one of you is in doubt about his prayer and he does not know how much he has prayed, whether it was three or four (Rak‘ahs), then he should cast aside his doubt and base his prayer on what he is certain of." Thus, one should consider the lesser number because it is what he is certain of, while the higher number of Rak‘ahs is subject to doubt. So one should cast aside doubt and act upon what he is certain of, which is the lesser number. The devil comes to the person while they are offering the prayer and whispers to them in order to make them think that they are no longer in a state of ritual purity. ‘Abdullāh ibn Zayd (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "The devil comes to one of you during the prayer and blows air in his bottom, making him think that he has broken his ablution." [Al-Bukhāri and Muslim] If this happens during the prayer, one has to say within himself that the devil has lied. He should not say this statement out loud, since speaking is not permitted during prayer; rather, it invalidates the prayer. The Messenger of Allah (may Allah's peace and blessings be upon him) said: "It is invalid to utter anything of people's speech inside this prayer." In conclusion, if the devil comes to someone while he is praying and whispers to him that he has broken his ablution, then he is to say within himself that the devil has lied and continue with his prayer and not exit it unless he is certain that he has invalidated his ablution due to detecting a smell or hearing a sound.
