Sayyiduna Jabir (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Whoever does not show mercy is not shown mercy; whoever does not forgive is not forgiven; and whoever does not repent, his repentance is not accepted."
(Allamah al-Haythami says:) I say: Part of this narration is mentioned in the Sahih.
Al-Tabarani recorded it, and Ahmad recorded it in abridged form, with these words: "Whoever does not repent, his repentance is not accepted." The narrators of Ahmad are the narrators of the Sahih.
