That you worship none but God. Lo! I fear for you should you worship other than Him the chastisement of a painful day’ painful in this world and in the Hereafter.
- 11:2626
أَنْ لَا تَعْبُدُوا إِلَّا اللَّهَ ۖ إِنِّي أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ أَلِيمٍ
Do not worship anyone but God; for I fear the punishment of a dreadful day for you."
