It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There is nothing for which Allah grants reward more quickly than maintaining ties of kinship; and transgression and severing ties of kinship bring punishment most quickly; and the false oath leaves homes desolate."
This hadith is well known as mursal.
