I heard the Prophet ﷺ saying, "Allah said, 'Who are most unjust than those who try to create something like My creation? I challenge them to create even a smallest ant, a wheat grain or a barley grain.' "
سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ قَالَ اللَّهُ ﷻ وَمَنْ أَظْلَمُ مِمَّنْ ذَهَبَ يَخْلُقُ كَخَلْقِي فَلْيَخْلُقُوا ذَرَّةً أَوْ لِيَخْلُقُوا حَبَّةً أَوْ شَعِيرَةً
