Tawhid (monotheism and exclusive obedience to Allah)

ٱتَّبِعُوا۟ مَآ أُنزِلَ إِلَيْكُم مِّن رَّبِّكُمْ وَلَا تَتَّبِعُوا۟ مِن دُونِهِۦٓ أَوْلِيَآءَ ۗ قَلِيلًا مَّا تَذَكَّرُونَ

Follow, [O mankind], what has been revealed to you from your Lord and do not follow other than Him any allies. Little do you remember.
