عَنْ طَارِقِ بْنِ شِهَابٍ قَالَ أَوَّلُ مَنْ قَدَّمَ الْخُطْبَةَ قَبْلَ الصَّلَاةِ مَرْوَانُ فَقَامَ رَجُلٌ فَقَالَ يَا مَرْوَانُ خَالَفْتَ السُّنَّةَ قَالَ تُرِكَ مَا هُنَاكَ يَا أَبَا فُلَانٍ فَقَالَ أَبُو سَعِيدٍ الْخُدْرِيُّ رَضِيَ اللَّهُ عَنْهُ أَمَّا هَذَا فَقَدْ قَضَى مَا عَلَيْهِ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ مَنْ رَأَى مِنْكُمْ مُنْكَرًا فَلْيُغَيِّرْهُ بِيَدِهِ فَإِنْ لَمْ يَسْتَطِعْ فَبِلِسَانِهِ فَإِنْ لَمْ يَسْتَطِعْ فَبِقَلْبِهِ وَذَلِكَ أَضْعَفُ الْإِيمَانِ
Sayyiduna Tariq bin Shihab says: The first person who delivered the sermon before the prayer was Marwan. A man stood up and said: O Marwan! You have opposed the Sunnah. He said: O Abu so-and-so! Those matters have been left behind. Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) said: This man has fulfilled his responsibility. I heard the Messenger of Allah (peace and blessings be upon him) say: Whoever among you sees an evil, let him change it with his hand; if he is not able to do so, then with his tongue; and if he is not able to do so, then with his heart, and that is the weakest level of faith.
