وَمِنْهُم مَّن يَقُولُ ائْذَن لِّي وَلَا تَفْتِنِّي ۚ أَلَا فِي الْفِتْنَةِ سَقَطُوا ۗ وَإِنَّ جَهَنَّمَ لَمُحِيطَةٌ بِالْكَافِرِينَ (49)
(9:49) There is such a one among them, who says, "Give me leave to stay behind and do not expose me to temptations. " *48 ---Note it well that such people have already succumbed to temptations *49 and Hell has encircled these disbelivers. *50
*48) Some of the hypocrites, who were requesting the Holy Prophet to give them leave to stay behind on one pretext or the other, were so impudent that they were inventing excuses of a religious or moral nature for refraining from jihad in the Way of Allah. One of these was Jad-bin-Qais, who, according to traditions came to the Holy Prophet and said. "I am a lover of beauty and my people know that I am very weak in regard to women: therefore I am afraid to go forth lest the beauty of the Roman women should beguile me into sin. Therefore ".... do not expose me to temptations."
*49) Though they wanted exemption, they had already fallen a prey to the temptations of telling lies, of double dealings and hypocrisy. They deluded themselves that they would be considered pious people, if they would put forward the fear of temptations to avoid Jihad, when, in fact; they had already fallen into the greatest possible temptation of refraining from Jihad in the conflict between Islam and kufr.
*50) That is, "Such a show of piety has not taken them away from Hell; nay, on the other hand, the same thing has caused them to be entangled in the clutches of Hell. "
