(2) Father told me long time back that I wish that my grave should be in Mumbai (Charni Road Qabrastan) because here many people come and pray for all the graves. But I was only one who knew this wish. I informed, but my 4 Chacha taken my father to Native next to Grandmother. I was in Riyadh and I told my brother do not wait for me as father daily used to pray for Jumuah Day. Did I do a mistake? Pray for my Father.

(1) Since Hajj was fardh on him; hence if he has not performed his fardh hajj earlier and he submitted his form for fardh hajj this year then it is necessary for his heirs to send anyone for Hajj-e-Badal on his behalf. They should send any pious person who has already performed his fardh hajj.
(2) It is not necessary to fulfil the wish of your father regarding the grave as per the Shariah. Hence his burial in the ancestral graveyard was alright. You did a good job as you asked your relatives not to wait you. It is the ruling of Shariah.
Allah knows Best!
