Musnad Ahmad 30:2743

Muhammad ibn Ja'far narrated to us, he said: Shu'bah narrated to us. And Hajjaj said: Shu'bah informed us. And 'Affan said: Shu'bah narrated to us, he said: I heard Muhammad ibn 'Abd al-Jabbar narrating from Muhammad ibn Ka'b, from Abu Hurayrah, from the Prophet, may Allah bless him and grant him peace, that he said: "Indeed, the womb (kinship) is a branch from the Most Merciful. It says: 'O Lord, I have been severed; O Lord, I have been wronged; O Lord, I have been treated badly; O Lord, O Lord.' So its Lord, Mighty and Majestic is He, answers it and says: 'Are you not pleased that I join whoever joins you, and I sever whoever severs you?'" Abu al-Walid narrated it to us, he said: Shu'bah narrated to us, from Muhammad ibn 'Abd al-Jabbar, he said: I heard Muhammad ibn Ka'b saying: I heard Abu Hurayrah saying: I heard the Messenger of Allah, may Allah bless him and grant him peace, saying: "Indeed, the womb..." and he mentioned the hadith. And 'Affan said in his hadith: Muhammad ibn 'Abd al-Jabbar is from the Ansar. He said: I heard Muhammad ibn Ka'b al-Qurazi saying: I heard Abu Hurayrah saying: I heard the Messenger of Allah, may Allah bless him and grant him peace.
