My name is MD Sadiqur Rahman. My name contains 'Rahman' which is one of the name which only belongs to Allah. Is there anything wrong if someone calls me with this name?
Naming children with names such as Rahman, Jabbar, Allah, etc., which are specific to the essence of God, is not good, but naming names such as Hamid, Ali, etc. is not a problem.
Of course, if you add the word 'Abd' at the beginning of God's special names to convey the meaning of serving God, such as "Abdullah, 'Abd al-Jabbar, etc., naming a child after him is not only okay, but is recommended by the Ahl al-Bayt.
Consequently, I think you'd better add the word "Abd" before Rahman, namely: Abd-Rahman (AbdulRahman)
Ar-rahman is the second 'name' of ALLAH. However, all the 99 'names' of ALLAH are in fact properties of HIM. These are all good properties, self-speakingly. So, it's also good if we people, as far as we can and are supposed to, should also incorporate them to find the best possible oneness with the Highest. Your name is a property that humans can thus should aim to have: to be gracious , French miséricordieux is a better fit. Ar-rahmani is exative, (of) the Most Gracious. Your name is only 'gracious'. In that sense you can accept it with honour and respect. Off cause the name ALLAH itself is the proper name, there only Abdullah, servant of ALLAH is possible.
