It is narrated from Sayyiduna Iyad al-Ansari (may Allah be pleased with him), who was a Companion, that the Messenger of Allah (peace and blessings be upon him) said: "Respect my rights regarding my Companions and my in-laws. Whoever respects my rights regarding them, Allah will protect him in this world and the Hereafter; and whoever does not respect my rights regarding them, Allah will abandon him, and whomever Allah abandons, it is near that He will seize him."
