Names and Nicknames
Question :
My name is Muhsin, which is one of Allah's Beautiful Names. Whenever somebody who knows me wishes to call me, he will say "Muhsin," a name that I cannot change since it is recorded in all official documents pertaining to me. Is it unlawful or Makruh (disliked) for me to have this name? And who carries the burden of the sin is it upon those who named me, or upon me?
Answer:
"Al-Muhsin" is one of Allah's attributes, and I do not know of it as being one of His names.Al-Ihsan (generosity and kindness), from which Al-Muhsin is derived. is a description of Allah's actions, and praise be to Allâh, one can have the name Muhsin as long as it is only intended as a name and not something that signifies anything further. One of the Prophet's Companions was known as Hakim, which is also one of Allah's names, and even though, the Prophet did not change his name. If your name signifies nothing other than a designation by which you are known, then it is permissible for you to continue to go by it.
