by Imam Muslim, translation by Abdul Hamid Siddiqui , Volume: The Book of Faith (Kitab Al-Iman)
Chapter: PERTAINING TO EVIIL SUGGESTION OR PROMPTING IN FAITH AND WHAT SHOULD BE SAID WHEN IT OCCURS TO THE MIND OF A MAN
It is narrated on the authority of Abu Huraira that some people from amongst the Companions of the Apostle (may peace be upon him) came to him and said: Verily we perceive in our minds that which every one of us considers it too grave to express. He (the Holy Prophet) said: Do you really perceive it? They said: Yes. Upon this he remarked: That is the faith manifest.
The same hadith has been transmitted by Muhammad b. 'Amr, Abu Baker b. Ishaq, Abu'l-Jawwab, A'mash and Abu Huraira.
It is narrated on the authority of 'Abdullah b. Mas'ud that the Apostle (may peace be upon him) was asked about evil prompting, to which he replied: It is pure faith.
It is narrated on the authority of Abu Huraira that the Messenger of Allah (may peace be upon him) said: Men will continue to question one another till this is propounded: Allah created all things but who created Allah? He who found himself confronted with such a situation should say: I affirm my faith in Allah.
This hadith has been transmitted by Mahmud b. Ghailan by another chain of transmitters (and the words are): The Messenger of Allah (may peace be upon him) said: The Satan will come to everyone of you and say: Who created the heaven, who created the earth? (And the man) replies: It is Allah, Then the remaining part of the hadith was narrated as mentioned above and the words 'His prophets" were added to it.
