49فَإِذا مَسَّ الإِنسانَ ضُرٌّ دَعانا ثُمَّ إِذا خَوَّلناهُ نِعمَةً مِنّا قالَ إِنَّما أوتيتُهُ عَلىٰ عِلمٍ ۚ بَل هِيَ فِتنَةٌ وَلٰكِنَّ أَكثَرَهُم لا يَعلَمونَ(Irfan-ul-Quran)When some suffering touches man, he cries to Us. But when We grant him some favour from Us he starts saying: ‘This favour has come to me on (the basis of my own) knowledge and planning.’ In fact it is a trial but most of them do not know.
