Re: Abdul or Abdur Rahim
Abdul Rahim would be ‘correct’, as Abdul means ‘banda’, and Abdur means nothing.
But in english, it would be a case of semantics, as at the end of the day, the name is actually arabic, and how you transliterate it into english will not change the meaning of it. To be on the safe side, Id say, Abdul Rahim.
Congratulations on the new arrival!
