An-Noor 24:63

Do not consider the Messenger’s summons to you as your summons to one another[37]. Allah surely knows those of you who slip away hiding behind others. So let those who disobey his command beware lest some trial[38] may afflict them or they may be afflicted with a painful punishment.

[37] i.e., Do not call him, ‘O Muhammad.’ Rather, call him, ‘O Prophet.’
[38] i.e., affliction, strife, dissension, etc.

Do not make [your] calling of the Messenger among yourselves as the call of one of you to another. Already Allāh knows those of you who slip away, concealed by others. So let those beware who dissent from his [i.e., the Prophet's] order,[1004] lest fitnah[1005] strike them or a painful punishment.

[1004] Meaning also his way or his sunnah.
[1005] Trials, affliction, dissension, strife, etc.

63. Make not the calling of the Messenger (Muhammad صلى الله عليه وسلم) among you as your calling one of another. Allâh knows those of you who slip away under shelter (of some excuse without taking the permission to leave, from the Messenger (صلى الله عليه وسلم). And let those who oppose the Messenger’s (Muhammad صلى الله عليه وسلم) commandment (i.e. his Sunnah - legal ways, orders, acts of worship, statements) (among the sects) beware, lest some Fitnah (disbelief, trials, afflictions, earthquakes, killing, overpowered by a tyrant) should befall them or a painful torment be inflicted on them.

Make not the calling of the messenger among you as your calling one of another. Allah knoweth those of you who steal away, hiding themselves. And let those who conspire to evade orders beware lest grief or painful punishment befall them.
