Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrated: the Prophet (peace and blessings be upon him) said: "Whoever has three things in him, Allah Almighty will take an easy reckoning from him and will admit him into Paradise by His mercy." He said: "O Messenger of Allah! May my father and mother be sacrificed for you, what are they?" the Prophet (peace and blessings be upon him) said: "That you give to the one who deprives you, keep ties with the one who cuts you off, and overlook the one who wrongs you." Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: "O Prophet of Allah! When I do this, what will I get?" the Prophet (peace and blessings be upon him) said: "When you do so, Allah Almighty will admit you into Paradise."
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Sulayman bin Dawud al-Yamami, who is da'if (weak).
