Is it permissible for a person to add a word to his name, such as someone named Salah adding the word al-Din?

The questioner : Well, Shaykh, a person naming himself, or rather adding a name to his name, for example, Salah, Salah al-Din, Nasser, Nasser al-Din, and so on.

The Shaykh : It is not permissible.

The questioner : It is not permissible.

The Shaykh : It is not permissible to name oneself in the first place, let alone add to it.

The questioner : Yes, if he names himself, does that mean he is considered a deceiver, or not?

The Shaykh : No, he is considered one who praises himself.

The questioner : Ah, one who praises himself. Yes, my name is Muhammad Nasser Najjar, so I liked to add Nasser al-Din, meaning to make my name resemble yours, and may Allah make my action like your action.

The Shaykh: No, no.

The questioner : So then I stopped to ask you about it.

The Shaykh : The one who named me like this was wrong!

The questioner: Ah, yes.

The Shaykh : Therefore, the correct thing is that I should be called Muhammad.

The questioner : Yes, we have this in Syria, Shaykh, where they add "Muhammad" for the sake of seeking blessing, so everyone is named Muhammad.

The Shaykh : This is well known.
