﴿ لَّا تَجْعَلُوا۟ دُعَآءَ ٱلرَّسُولِ بَيْنَكُمْ كَدُعَآءِ بَعْضِكُم بَعْضًۭا ۚ قَدْ يَعْلَمُ ٱللَّهُ ٱلَّذِينَ يَتَسَلَّلُونَ مِنكُمْ لِوَاذًۭا ۚ فَلْيَحْذَرِ ٱلَّذِينَ يُخَالِفُونَ عَنْ أَمْرِهِۦٓ أَن تُصِيبَهُمْ فِتْنَةٌ أَوْ يُصِيبَهُمْ عَذَابٌ أَلِيمٌ ﴾

“DO NOT regard the Apostles summons to you [in the same light] as a summons of one of you to another: God is indeed aware of those of you who would withdraw surreptitiously: so let those who would go against His bidding beware, lest a [bitter] trial befall them [in this world] or grievous suffering befall them [in the life to come].”

(Make not the calling of the messenger among you) i.e. do not call the Prophet (pbuh) by his name saying: O Muhammad, (as your calling one of another) by name. You should rather respect him, show deference towards him and honour him by saying: " O Prophet of Allah " , " O Messenger of Allah " , " O Abu'l-Qasim ": (Allah knoweth those of you who steal away) from the mosque, (hiding themselves) the hypocrites used to leave the mosque without permission when no one could see them. (And let those who conspire to evade orders) the orders of the Messenger of Allah (pbuh); it is also said that this means: the orders of Allah (beware lest grief) a calamity (or painful punishment) beating (befall them.
