Allah the Exalted says to His Prophet, Muhammad ,

[إِنَّآ أَرْسَلْنَـكَ شَاهِداً]

(Verily, We have sent you as a witness,) of the creation,

[وَمُبَشِّراً]

(as a bearer of glad tidings,) to the believers,

[وَنَذِيرًا]

(and as a warner.) to the disbelievers. We explained these meanings in the Tafsir of Surat Al-Ahzab. Allah said,

[لِّتُؤْمِنُواْ بِاللَّهِ وَرَسُولِهِ وَتُعَزِّرُوهُ]

(In order that you may believe in Allah and His Messenger, and that you Tu`azziruh) or you honor him, according to `Abdullah bin `Abbas and several others,

[وَتُوَقِّرُوهُ]

(and Tuwaqqiruh), where Tawqir means, respect, honor and high regard,

[وَتُسَبِّحُوهُ]

(and that you Tusabbihuh), glorify Allah's praises,

[بُكْرَةً وَأَصِيلاً]

(Bukrah and Asila), the early and late part of the day.
