Names and appellations in the Qur'an

Names and appellations in the Qur'an:
The name Muhammad(saw) means "Praiseworthy" and occurs four times in the Qur'an.^[17] The Qur'an addresses Muhammad(saw) in the second person not by his name but by the appellations prophet, messenger, servant of Allah ('abd), announcer (bashir), warner (nathir), reminder (mudhakkir), witness (shahid), bearer of good tidings (mubashshir), one who calls [unto Allah] (dā‘ī) and the light-giving lamp (siraj munir). Muhammad(saw) is sometimes addressed by designations deriving from his state at the time of the address: thus he is referred to as the enwrapped (al-muzzammil) in Qur'an 73:1 and the shrouded (al-muddaththir) in Qur'an 74:1.^[18] In the Qur'an, believers are not to distinguish between the messengers of Allah and are to believe in all of them (Sura Al-Baqara 2:285). Allah has caused some messengers to excel above others 2:253 and in Sura Al-Ahzab 33:40 He singles out Muhammad(saw) as the "Seal of the Prophets".^[19] The Qur'an also refers to Muhammad(saw) as Ahmad "more praiseworthy" (Arabic: أحمد‎, Sura As-Saff 61:6).
