Sahih Muslim Book - 1, Hadith - 177

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا وَكِيعٌ عَنْ سُفْيَانَ ح و حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ كِلَاهُمَا عَنْ قَيْسِ بْنِ مُسْلِمٍ عَنْ طَارِقِ بْنِ شِهَابٍ وَهَذَا حَدِيثُ أَبِي بَكْرٍ قَالَ أَوَّلُ مَنْ بَدَأَ بِالْخُطْبَةِ يَوْمَ الْعِيدِ قَبْلَ الصَّلَاةِ مَرْوَانُ فَقَامَ إِلَيْهِ رَجُلٌ فَقَالَ الصَّلَاةُ قَبْلَ الْخُطْبَةِ فَقَالَ قَدْ تُرِكَ مَا هُنَالِكَ فَقَالَ أَبُو سَعِيدٍ أَمَّا هَذَا فَقَدْ قَضَى مَا عَلَيْهِ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَنْ رَأَى مِنْكُمْ مُنْكَرًا فَلْيُغَيِّرْهُ بِيَدِهِ فَإِنْ لَمْ يَسْتَطِعْ فَبِلِسَانِهِ فَإِنْ لَمْ يَسْتَطِعْ فَبِقَلْبِهِ وَذَلِكَ أَضْعَفُ الْإِيمَانِ.

It was narrated that Tariq bin Shihab - and this is the Hadith of Abu Bakr (one of the narrators) - said: "The first one to start with the Khutbah on the day of 'Eid, before the prayer, was Marwan. A man stood up and said: '(Shouldn't) the prayer (come) before the Khutbah?' He said: 'What was there has been left.' Abu Sa'eed said: 'This man has done his duty. I heard the Messenger of Allah (s.a.w) say: "Whoever among you sees an evil action, let him change it with his hand (by taking action); if he cannot, then with his tongue (by speaking out) ; and if he cannot, then with his heart (by hating it and feeling it is wrong), and that is the weakest of faith."
