I caught myself giving somebody fewer than 70 excuses this weekend. It's one of those things that's easier said than done. "What 7o excuses" you ask?
Hamdun al-Qassar, one of the great early Muslims, as narrated by Imam Bayhaqi in his Shu`ab al-Iman [7.522].
He said (Allah have mercy on him),
"If a friend among your friends errs, make seventy excuses for them. If your hearts are unable to do this, then know that the shortcoming is in your own selves." Id.
