Question: I performed Hajj on behalf of my mother after her death, and did not perform Hajj for my father after his death. So is there any sin upon me for having left off performing Hajj for my father?
Response: There is no sin upon you for having left off performing Hajj for your father. This is because it is not obligatory upon you to perform Hajj on his behalf. However, from honouring and being good (to your father) is to perform Hajj on his behalf, as this is incorporated in the general statement of ihsaan (doing good) which Allaah has commanded in His saying:
{And be dutiful to your parents}, [Soorah al-Israa., Aayah 23].
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet ﷺ and his family and his companions.
