بسم الله الرحمن الرحيم
(Fatwa: 568/496/SD=6/1438)
You should add the word Abd with the name of Allah for example: Abdullah, Abdur Rahman, Abdur Rahim, Abdus Sami or keep any name after the names of Prophets or Companions for example, Muhammad, Musa, Isa, Umar, Khalid, Usman etc. Ashaz and Shaz are not good to keep as some one’s name.
Allah knows Best!
