It is narrated on the authority of Tariq bin Shihab: 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 ( صلی اللہ علیہ وسلم ) 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.

The same hadith of the Holy Prophet ( صلی اللہ علیہ وسلم ) (may peace and blessings be upon him) has been reported by Abu Sa'id al-Khudri in connection with the story of Marwan.

It is narrated on the authority 'Abdullah bin Mas'ud that the Messenger of Allah ( صلی اللہ علیہ وسلم ) (may peace and blessings be upon him) observed: Never a Prophet ( صلی اللہ علیہ وسلم ) 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 bin 'Umar; he contradicted me. There happened to come 'Abdullah bin Mas'ud who stayed at Qanat, and 'Abdullah b 'Umar wanted me to accompany him for visiting him (as 'Abdullah bin 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.

The same hadith has been transmitted by another chain of narrators on the authority of 'Abdullah bin Mas'ud who observed: Never was there one among the prophets who had had not disciples who followed his direction and followed his ways. The remaining part of the hadith is like that as narrated by Salih but the arrival of Ibn Mas'ud and the meeting of Ibn 'Umar with him is not mentioned.
