The same hadith of the Prophet (may peace and blessings be upon him) has been reported by Abu Sa'id al-Khudri in connection with the story of Marwan.
Sahih Muslim Book 1, Hadith 85
← Previous Hadith
It was Marwan who initiated (the practice) of delivering khutbah (address) before the prayer on the 'Id day. A man stood up and said: Prayer should precede khutbah. He (Marwan) remarked, This (practice) has been done away with. Upon this Abu Sa'id remarked: This man has performed (his duty) laid on him. I heard the Messenger of Allah as saying: He who amongst you sees something abominable should modify it with the help of his hand; and if he has not strength enough to do it, then he should do it with his tongue, and if he has not strength enough to do it, (even) then he should (abhor it) from his heart, and that is the least of faith.
Sahih Muslim Book 1, Hadith 84 Next Hadith → Never a Prophet had been sent before me by Allah towards his nation who had not among his people (his) disciples and companions who followed his ways and obeyed his command. Then there came after them their successors who said whatever they did not practise, and practised whatever they were not commanded to do. He who strove against them with his hand was a believer: he who strove against them with his tongue was a believer, and he who strove against them with his heart was a believer and beyond that there is no faith even to the extent of a mustard seed. Abu Rafi' said: I narrated this hadith to 'Abdullah b. 'Umar; he contradicted me. There happened to come 'Abdullah b. Mas'ud who stayed at Qanat, and 'Abdullah b 'Umar wanted me to accompany him for visiting him (as 'Abdullah b. Mas'ud was ailing), so I went along with him and as we sat (before him) I asked Ibn Mas'ud about this hadith. He narrated it in the same way as I narrated it to Ibn 'Umar.
