Praise be to Allaah.
There is nothing wrong with
using the name Yazan, because there is no reason not to do so in sharee’ah.
Yazan is the name of a valley in Yemen. It says in al-Qamoos al-Muheet:
Yazan is a valley, the original name of which was Yaz’an; it is also the
name of a tribe from Himyar. Dhu Yazan was a king of Himyar because he
protected that valley. End quote.
So it is the name of a valley
and the name of a tribe from Himyar.
But it would be better than
that to call the child ‘Abd-Allaah or ‘Abd al-Rahmaan or Ahmad or Muhammad,
or the name of one of the Sahaabah, or a name that carries a good meaning.
This is better than calling him by the name of a valley.

And Allaah knows best.
