Re: mohammed ali
People have been putting Muhammad before the names of their sons in Pakistan for a long time. None of them call their sons by this name. It seems to me that it is an excuse to have the name in wiriting and not having to actually call their children by that name.
Peace sana
If you want to call a baby Muhammad ...which is a beautiful name .... then call him Muhammad, otherwise having Muhammad there and only calling him by his second name only goes as far as the papers. If you want to call him Ali then ... his name is Ali son of [Father's name] otherwise if you have a family name or zaat name then use that but having a prefix name that you will never call ... it is not fair to that name.
