Musnad Ahmad 30:2150

'Affan narrated to us, he said: Shu'bah narrated to us, he said: Muhammad ibn al-Jabbar informed me, he said: I heard Muhammad ibn Ka'b al-Qurazi narrating that he heard Abu Hurayrah saying: I heard the Messenger of Allah, peace and blessings of Allah be upon him, saying: "Indeed, the womb (kinship) is a branch from the Most Merciful. It says: 'O Lord, I have been severed; O Lord, I have been treated badly; O Lord, I have been wronged; O Lord.'" He said: "So He answers it: 'Are you not pleased that I should join whoever joins you, and sever whoever severs you?'"
