Narrated Muawiyah: I heard the Messenger of Allah ﷺ say: If you search for the faults of the people, you will corrupt them, or will nearly corrupt them. Abud Darda said: These are the words which Muawiyah himself from the Messenger of Allah ﷺ, and Allah benefited him by them.
Explanation & Benefits
Shaykh Umar Farooq Saeedi
Benefits and Issues:
➊ It is entirely possible that people, due to their faults being exposed, may become even more audacious and begin to commit wrong actions openly. However, if a just Imam seeks out such information for the purpose of advice and rectification of affairs, then it is permissible.
➋ Just as this Prophetic instruction benefited Sayyiduna Mu'awiyah (radi Allahu anhu) and he remained a successful leader, in the same way, all members of the Ummah can benefit by following his example.
