"[That you not worship except Allah. Indeed, I am to you from Him a warner]"—He says to the Prophet, peace be upon him: Say: Do not worship anyone except Allah. Indeed, I am to you a warner from Him, warning you of His punishment if you do not believe, "and a bringer of good tidings" of Paradise for those who believe.
﴿أَلَّا تَعْبُدُوا إِلا اللَّهَ إِنَّنِي لكم مِنْهُ نَذِير﴾ يَقُولُهُ لِلنَّبِيِّ ﷺ قُلْ:
لَا تَعْبُدُوا إِلا اللَّهَ؛ إِنَّنِي لَكُمْ مِنْهُ نَذِيرٌ؛ أُنْذِرَكُمْ عِقَابَهُ إِنْ لَمْ تُؤْمِنُوا ﴿وَبَشِيرٌ﴾ بِالْجنَّةِ لمن آمن.
