Al-Mu'jam al-Awsat 5758 — the Ansar said among themselves: If only we

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Ansar said among themselves: "If only we would gather some wealth for the Messenger of Allah (peace and blessings be upon him), so that he (peace and blessings be upon him) could take it in his blessed hand and spend it wherever he wishes, with nothing coming between him (peace and blessings be upon him) and that wealth." So they said: "O Messenger of Allah, we intend to gather something for you from our wealth." Then Allah, the Mighty and Majestic, revealed this verse: "Say: I do not ask you for any reward for it except love for kinship." Then they went out disagreeing among themselves and saying: "Did you not see what the Messenger of Allah (peace and blessings be upon him) has said?" Some of them said: "He (peace and blessings be upon him) said this only so that we would fight on behalf of his (peace and blessings be upon him) household and help them." So Allah, the Mighty and Majestic, revealed these verses, from: "Or do they say that he has invented a lie against Allah?" up to: "And it is He who accepts repentance from His servants." In this way Allah Almighty pointed them towards repentance, until He said: "And He responds to those who believe and do righteous deeds, and gives them more out of His bounty." This refers to those very people who had said that, (meaning) that they should repent to Allah and seek His forgiveness.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Uthman Abu al-Yaqzan except Nusayr bin Ziyad, and Husayn al-Ashqar is alone in narrating it."
