I changed my surname due as my father’s surname is not a Muslim surname. He converted but did not change his name. I did not want my children to have the difficulty as I had growing up being teased/mocked as a result of having a Non-Muslim surname. Please help as would like to know how I would be called on the day of Qiyaamat.
On the day of Qiyaamat, one will not be called by his surname. Thus, the change of your surname does not matter.
and Allah Ta’ala Knows Best
