Alhamdulillah for having friends who posts good reminders when you need them the most.
Your own sins should distract you enough from focusing on the faults of others.
Stay conscious of your flaws.. the greatest men who lived done more for Islam than you and I could imagine, yet they still saw their sins higher than mountains and always felt like they could do more in terms of their good deeds. So take lesson and remember it’s healthy to realise what you do not know, and what you still can and need to do.
"If you see that one of you has slipped, correct him, pray for him and do not help shaytaan against him (by insulting him)" - Umar ibn Al Khattab
Imam Sufyaan ath-Thawri (rahimahullah) advised one of his Brothers:
“Today, people are not able to discern between truth and falsehood, and none will be saved from this predicament except for someone who invokes Allah with the same intensity and feeling with which a drowning man invokes Allah for help. Do you know anyone who is at that level?It used to be said: ‘The time draws near for the people when the wise among them will find no joy (but will instead be constantly worried about the degeneration of Muslim society).’ Fear Allah, the Possessor of might and majesty. Be a man of solitude; occupy your time with yourself (with preparing for the Hearafter); and seek companionship with the Book of Allah (Azza wa Jal).”
