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.
