Q: My question is on the day of judgement we will be called with our calling names or with the name which is shouted in the ear of new born baby? And my second question is during the period of jesus (Alayhis Salaam) will it be compulsory on the present muslims to join them?
A: The name that you are known with, your name and the name of parents.
Every Muslim will feel obliged to follow him and respect him as per the command of Nabi (sallallahu alaihi wa sallam).
And Allah Ta’ala (الله تعالى) knows best.
عن أبى الدرداء قال قال رسول الله -صلى الله عليه وسلم- إنكم تدعون يوم القيامة بأسمائكم وأسماء آبائكم فأحسنوا أسماءكم (أبو داود #4950)
