Abdullah Ibn ‘Umar رضي الله عنهما: “If we did not see a person at Fajr and ‘Ishā prayers, we would think badly of him.” [المعجم الكبير للطبراني ١٢\٢٧١]
Narrated `Umar bin Al-Khattab: People were (sometimes) judged by the revealing of a Divine Inspiration during the lifetime of Allah’s Messenger ﷺ but now there is no longer any more (new revelation). Now we judge you by the deeds you practice publicly, so we will trust and favor the one who does good deeds in front of us, and we will not call him to account about what he is really doing in secret, for Allah will judge him for that; but we will not trust or believe the one who presents to us with an evil deed even if he claims that his intentions were good.
Abu Sa'id Al-Khudri (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, “Whoever amongst you sees an evil, he must change it with his hand; if he is unable to do so, then with his tongue; and if he is unable to do so, then with his heart; and that is the weakest form of Faith.”
فالأول: عن أبي سعيد الخدري رضي الله عنه قال: سمعت رسول الله صلى الله عليه وسلم يقول: “من رأى منكم منكرًا فليغيره بيده ، فإن لم يستطع فبلسانه، فإن لم يستطع فبقلبه وذلك أضعف الإيمان" ((رواه مسلم)).
