The Prophet ﷺ called out: “O you who believed with your tongues but faith has not entered your hearts: do not harm the Muslims, nor seek out their faults, for whoever seeks out his brother's faults, Allah will seek out his — and expose him even in his own house.” (Abū Dāwūd — ṣaḥīḥ). Busy yourself with your own faults.
العربية: عن ابن عمر رضي الله عنهما أنّ النبيّ ﷺ نادى: «يا معشر من أسلم بلسانه ولم يدخل الإيمان قلبه: لا تؤذوا المسلمين ولا تتّبعوا عوراتهم، فإنّ من تتبّع عورة أخيه المسلم تتبّع الله عورته». (أبو داود).
Don't chase or repeat people's mistakes — cover them, and mind your own.
