أَلَهُمْ أَرْجُلٌۭ يَمْشُونَ بِهَآ ۖ أَمْ لَهُمْ أَيْدٍۢ يَبْطِشُونَ بِهَآ ۖ أَمْ لَهُمْ أَعْيُنٌۭ يُبْصِرُونَ بِهَآ ۖ أَمْ لَهُمْ ءَاذَانٌۭ يَسْمَعُونَ بِهَا ۗ قُلِ ٱدْعُوا۟ شُرَكَآءَكُمْ ثُمَّ كِيدُونِ فَلَا تُنظِرُونِ
Have they feet wherewith they walk, or have they hands wherewith they hold, or have they eyes wherewith they see, or have they ears wherewith they hear? Say: Call upon your (so-called) partners (of Allah), and then contrive against me, spare me not!
