Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Whoever would be pleased to have lofty buildings raised for him (in Paradise) and his ranks elevated, let him pardon the one who wronged him, give to the one who deprived him, and join ties with the one who cut him off."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Musa except Abu Umayyah, Hajjaj is alone in narrating it, and this report is narrated from Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) only with this chain."
