Sami Yusuf is a religious singer. "Hasbi Rabbi" is the first song I'v heard. Then I fond of other songs dan became his fan.   Masyaa Allah, really interesting to me. I have three albums "Al Mu'alim, Mu Ummah and Salaam".  All lyrics very beautiful amazing, there are blessings, and invite us to remember Allah and Prophet Muhammad ( peace and blessings of Allah be upon him).
