Sayyiduna Ja’far ibn Muhammad As Sadiq (rahimahullah) said: “If something that you dislike reaches you about your brother then search for an excuse for him, up to seventy excuses. If it hits the mark, [then good]. If not, Then say, ‘Perhaps he has an excuse that I am not aware of.'”
Imam Bayhaqi (rahimahullah) has recorded this narration in Shu’abul Iman.
