I heard the Messenger of Allah ﷺ say, "Whoever sees a wrong and changes it with his hand has absolved himself. Whoever is unable to change it with his hand and changes it with his tongue has absolved himself. And whoever is unable to change it with his tongue and changes it with his heart has absolved himself, and that is the weakest of faith."
حدثنا عبد الحميد بن محمد قال حدثنا مخلد قال حدثنا مالك بن مغول عن قيس بن مسلم عن طارق بن شهاب قال
سمعت رسول الله ﷺ يقول من رأى منكرا فغيره بيده فقد برئ ومن لم يستطع أن يغيره بيده فغيره بلسانه فقد برئ ومن لم يستطع أن يغيره بلسانه فغيره بقلبه فقد برئ وذلك أضعف الإيمان
