in front of the rulers....Shaikh or Emir with His Highness (H.H) and His Excellency (H.E) with all other ministers....pls note prophets can never be compared to rulers/ministers.

Don't follow the dictionary...as you assumed Prophets are men BUT chosen gentlemen by Allah and much much more respectful then where we/common men stand; so it is obligatory for us to call their names with highly respectful manner e.g Prophet Musa (Alaih Salaam) or Prophet Moses (Peace be on Him). Nothing personal but this is important and it matters in our religion.

Rest tomorrow, quite busy at work.
