Majma al-Zawaid — Hadith 13635

Sayyidah Aishah Siddiqah (may Allah be pleased with her) narrates: the Prophet (peace and blessings be upon him) would often ask me: "O Aishah, what has become of your verses?" I would say: "O Messenger of Allah, which of my verses do you mean? For they are many." the Prophet (peace and blessings be upon him) said: "Those on gratitude." I said: "Yes, may my father and mother be sacrificed for you. The poet said: 'Raise up your weak one in such a way that his weakness does not harm you one day, and that the consequences reach him when he has grown. He will repay you or praise you, and whoever praises you for what you did is like one who has repaid you. When you seek a bond with a noble person, you will not find his rope worn out, with weak strands.'" The Prophet (peace and blessings be upon him) said: "O Aishah, on the Day of Resurrection, when Allah Almighty gathers the creation, He will ask one of His servants to whom one of Allah's servants had done some good: 'Were you grateful to him?' That person will reply: 'O my Lord, I knew that this good was from You, so I thanked You for it.' Allah Almighty will say: 'You have not thanked Me, since you were not grateful to the one through whom I granted you that good.'"
Al-Tabarani recorded it in al-Mu'jam al-Saghir and al-Mu'jam al-Awsat from his teacher Dhakir bin Shaybah al-Asqalani, whom al-Azdi declared da'if (weak).
