"‏ مَنْ رَأَى مِنْكُمْ مُنْكَرًا فَاسْتَطَاعَ أَنْ يُغَيِّرَهُ بِيَدِهِ فَلْيُغَيِّرْهُ بِيَدِهِ فَإِنْ لَمْ يَسْتَطِعْ فَبِلِسَانِهِ فَإِنْ لَمْ يَسْتَطِعْ فَبِقَلْبِهِ وَذَلِكَ أَضْعَفُ الإِيمَانِ ‏"

“Marwan brought out the pulpit on the day of ‘Eid, and he started with the sermon before the prayer. A man said: ‘O Marwan, you have gone against the Sunnah. You have brought out the pulpit on this day, and it was not brought out before, and you have started with the sermon before the prayer, and this was not done before.’ Abu Sa’eed said: ‘As for this man, he has done his duty. I heard the Messenger of Allah (ﷺ) say: ‘Whoever among you sees an evil action and can change it with his hand (by taking action), let him change it with his hand. If he cannot do that, then with his tongue (by speaking out); and if he cannot do that, then with his heart (by hating it and feeling that it is wrong), and that is the weakest of faith.’”
