It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Kinship (rahim) is a branch attached to the hem of the power of Allah, the Most Merciful, which beseeches Allah Almighty for its right. Allah Almighty says: Are you not pleased that I join with My mercy whoever joins you, and cut off from My mercy whoever severs you? And whoever joins you has indeed joined Me, and whoever cuts you off has indeed cut off ties with Me."
Imam Abu Bakr bin Abi Shaybah narrated this report in his Musnad; the narrator Musa bin Ubaydah al-Rabadhi in its chain is da'if (weak), but supporting reports on the virtue of maintaining kinship ties exist in the two Sahihs.
