Names and appellations in the Quran

The name Muhammad means "Praiseworthy" and occurs four times in the Quran.^[25] The Quran addresses Muhammad in the second person not by his name but by the appellations prophet, messenger, servant of God ('abd), announcer (bashir)^{[Quran 2:119]}, witness (shahid),^{[Quran 33:45]} bearer of good tidings (mubashshir), warner (nathir),^{[Quran 11:2]} reminder (mudhakkir),^{[Quran 88:21]} one who calls [unto God] (dā‘ī),^{[Quran 12:108]} light personified (noor)^{[Quran 05:15]}, and the light-giving lamp (siraj munir)^{[Quran 73:1]}. Muhammad 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 Quran 73:1 and the shrouded (al-muddaththir) in Quran 74:1.^[26] In the Quran, believers are not to distinguish between the messengers of God and are to believe in all of them (Sura Al-Baqara 2:285). God has caused some messengers to excel above others 2:253 and in Sura Al-Ahzab 33:40 He singles out Muhammad as the "Seal of the Prophets".^[27] The Quran also refers to Muhammad as Aḥmad "more praiseworthy" (Arabic: أحمد‎, Sura As-Saff 61:6
