Is the word "wiladat" allowed?
Because someone has raised the issue that we should not use the word wiladat when talking about the birth anniversaries of the ahlebait (a.s). Wiladat is wrong. We need to use the word Nazool instead.

This is a form of hyperbole, the Imams peace be upon them were born for a father and a mother and did not descend from heaven, and they themselves used the word wiladat.
Imam Redha A.S. said: I will be born a boy.
