Allah's Oneness (Tawhid)

قُلْ مَن يَكْلَؤُكُم بِٱلَّيْلِ وَٱلنَّهَارِ مِنَ ٱلرَّحْمَـٰنِ ۗ بَلْ هُمْ عَن ذِكْرِ رَبِّهِم مُّعْرِضُونَ

Say, "Who can protect you at night or by day from the Most Merciful?" But they are, from the remembrance of their Lord, turning away.

وَمَا قَدَرُوا۟ ٱللَّهَ حَقَّ قَدْرِهِۦ وَٱلْأَرْضُ جَمِيعًا قَبْضَتُهُۥ يَوْمَ ٱلْقِيَـٰمَةِ وَٱلسَّمَـٰوَٰتُ مَطْوِيَّـٰتٌۢ بِيَمِينِهِۦ ۚ سُبْحَـٰنَهُۥ وَتَعَـٰلَىٰ عَمَّا يُشْرِكُونَ

They have not appraised Allāh with true appraisal, while the earth entirely will be [within] His grip on the Day of Resurrection, and the heavens will be folded in His right hand. Exalted is He and high above what they associate with Him.

وَلَئِن سَأَلْتَهُم مَّنْ خَلَقَهُمْ لَيَقُولُنَّ ٱللَّهُ ۖ فَأَنَّىٰ يُؤْفَكُونَ

And if you asked them who created them, they would surely say, "Allāh." So how are they deluded?
