Mukhtasar Bukhari

Narrated by Sayyiduna Abu Huraira (may Allah be pleased with him): The Prophet Muhammad (peace and blessings be upon him) said: "The womb (rahm) is derived from the Most Merciful (Rahman). (That is, the bond of kinship is connected and joined to Allah, the Most Merciful.) Therefore, Allah the Exalted said (regarding the bond of kinship): 'Whoever joins you, I will join him, and whoever severs you, I will sever him.'"
