The Prophet ﷺ was asked about intrusive whisperings, and he said, "That is pure faith."
سئل النبي ﷺ عن الوسوسة، قال: تلك محض الإيمان.
Reported by Muslim in the Book of Faith (133), from Yusuf bin Yaqub Saffar, who said, Ali bin Utham told me, from Suayr bin Khams, from Mughira bin Miqsam, from Ibrahim, from Alqama, from Abdullah, and he related the hadith.Baghawi also reported it in his "commentary" (59) through another route, from Muhammad bin Abdul-Wahhab, who said, I heard Ali bin Utham say, I came to Suayr bin Khams and asked him about the hadith on intrusive thoughts, but he did not relate it to me. So I turned away weeping, then he met me and said to me, "Come, let me tell you." He related to us from Mughira, from Ibrahim, from Alqama, from Abdullah, who said, We asked the Messenger of Allah ﷺ about a man who experiences something such that if he fell from the sky and were snatched up by birds, that would be dearer to him than speaking of it. The Prophet ﷺ said, "That is pure faith" or "clear faith."Khattabi said, "His statement, 'clear faith,' means that clear faith is what prevents you from accepting what Satan casts into your souls, and from believing it. It does not mean that the intrusive thought itself is clear faith, since such thoughts are only generated by the action and enticement of Satan, so how could they be clear faith? It has been related in another hadith that when they complained to him about this, he said, 'Praise be to Allah, who reduced his scheme to mere intrusive thoughts.'" This is the hadith of Ibn Abbas that follows.Nawawi said, "Its meaning is that your regarding it as a grave matter to speak of it is itself clear faith, for regarding this as grave and having intense fear of it, and of uttering it, let alone believing it, only occurs in one whose faith has become truly complete, and from whom doubt and uncertainty have been removed."
