Hadith: Faults of others

"Thinking about things that one shouldn't be thinking about is considered prohibited. Including that would be weaknesses/faults of Muslims whether they be absent or present. A hadith: there's a tree in paradise for the one whose preoccupation with his OWN faults causes him to forget the faults of others. Everybody's got faults & if you start thinking about other peoples' faults, you're just a fool." - Hamza Yusuf
