Musnad Ahmad 30:813

Yazid ibn Harun narrated to us, Shu'bah ibn al-Hajjaj informed us, from Muhammad ibn 'Abd al-Jabbar, from Muhammad ibn Ka'b al-Qurazi, from Abu Hurayrah, from the Prophet, may Allah bless him and grant him peace, that he said: "The womb (kinship) is a branch from the Most Merciful, Mighty and Majestic is He. It will come on the Day of Resurrection and say: 'O Lord, I have been severed! O Lord, I have been wronged! O Lord, I have been treated badly!'"
