النّور — An-Nur Ayat 63
لَا تَجْعَلُوْا دُعَاۤءَ الرَّسُوْلِ بَيْنَكُمْ كَدُعَاۤءِ بَعْضِكُمْ بَعْضًاۗ قَدْ يَعْلَمُ اللّٰهُ الَّذِيْنَ يَتَسَلَّلُوْنَ مِنْكُمْ لِوَاذًاۚ فَلْيَحْذَرِ الَّذِيْنَ يُخَالِفُوْنَ عَنْ اَمْرِهٖٓ اَنْ تُصِيْبَهُمْ فِتْنَةٌ اَوْ يُصِيْبَهُمْ عَذَابٌ اَلِيْمٌ
Lā taj‘alū du‘ā'ar-rasūli bainakum kadu‘ā'i ba‘ḍikum ba‘ḍā(n), qad ya'lamullāhul-lażīna yatasallalūna minkum liwāżā(n), falyaḥżaril-lażīna yukhālifūna ‘an amrihī an tuṣībahum fitnatun au yuṣībahum ‘ażābun alīm(un).
"Do not make [your] calling of the Messenger among yourselves as the call of one of you to another. Already Allah knows those of you who slip away, concealed by others. So let those beware who dissent from the Prophet's order, lest fitnah strike them or a painful punishment."
