In The Name of Allaah, The Most Merciful, The Bestower of Mercy

Imaam Fudayl Ibn Iyaad (rahimahullaah) once cried when he read the statement of Allaah [The Most High]: [أَلَمۡ نَجۡعَل لَّهُ ۥ عَيۡنَيۡنِ-Have We not made for him (i.e. the human) a pair of eyes?][ وَلِسَانً۬ا وَشَفَتَيۡنِ -And a tongue and a pair of lips?] [Ref 1]; then he was asked the reason he cried, so he said, ”Have you spent a night really thanking Allaah (for giving) you  two eyes by way of which you can see and a tongue by way of which you speak?’’  [Ref 2]
