Musannaf Ibn Abi Shayba 17:92

Yazid ibn Harun narrated to us, from Shu'bah, from Muhammad ibn al-Jabbar, from Muhammad ibn Ka'b al-Qurazi, from Abu Hurayrah, from the Prophet, peace and blessings of Allah be upon him, who said: "Kinship (al-rahim) is a branch (shujnah) from the Most Merciful (al-Rahman). It will come on the Day of Resurrection and say: 'O Lord, I have been severed! O Lord, I have been severed! O Lord, I have been treated badly!'"
