Kulaib bin Manfa‘ah narrates that his grandfather (Bakr bin Harith Ansari) submitted: O Messenger of Allah! With whom should I show good conduct? The Prophet (peace be upon him) said:“Show good conduct to your mother, your father, your sister, and your brother. And show good conduct to other relatives besides them as well. This is a due right, and maintaining ties of kinship and upholding family relations is obligatory.”
