It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Sins are of three kinds: a sin that will be forgiven, a sin that will not be forgiven, and a sin that will be requited. The sin that will not be forgiven is associating partners with Allah (shirk); the sin that will be forgiven is your deeds that are between you and your Lord; and the one that will be requited is your wronging your brother."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ata except Talhah bin Amr."
