إِنَّهُ لَيْسَ شَيْءٌ فِيهِ قَبْضٌ أَوْ بَسْطٌ مِمَّا أَمَرَ اللَّهُ بِهِ أَوْ نَهَى عَنْهُ إِلَّا وَ فِيهِ لِلَّهِ عَزَّ وَ جَلَّ ابْتِلَاءٌ وَ قَضَاءٌ[1].
“ There is nothing in which there is expansion or reduction of the matters that Allah has commanded or has prohibited except that Allah, the Most Holy, the Most High, therein has a decree and a testing.”
