يَا أَيُّهَا الَّذِينَ آمَنُوا مَا لَكُمْ إِذَا قِيلَ لَكُمُ انفِرُوا فِي سَبِيلِ اللَّهِ اثَّاقَلْتُمْ إِلَى الْأَرْضِ ۚ أَرَضِيتُم بِالْحَيَاةِ الدُّنْيَا مِنَ الْآخِرَةِ ۚ فَمَا مَتَاعُ الْحَيَاةِ الدُّنْيَا فِي الْآخِرَةِ إِلَّا قَلِيلٌ (38)
(9:38) O *38 you who believed! what was amiss with you that, when you were asked to march forth on the Way of Allah, you clung to the earth? What! did you prefer the life of this world to the life of the Hereafter? If it is so, you should know that all these goods of this worldly life will prove to be but little in the Hereafter. *39
*38) From here begins the discourse (vv. 38-72) which was sent down at the time when the Holy Prophet was engaged in making preparations for the Campaign to Tabuk.
*39) ".... you should know that the goods ... Hereafter" may imply two meanings. First: "When you will find that the life in the Hereafter is eternal and see that the good things and the provisions of enjoyment are countless, you will realize that the potential and the actual enjoyments of the temporary life of this world were nothing as compared with the blessings of that great Kingdom. At that time you will regret why you deprived yourselves of this everlasting happiness and bliss for the sake of the little-very little-sort-lived enjoyments of the mortal life of this world. " Second: "The goods of this worldly life are of no value in the Hereafter, howsoever abundant they might be. You shall have to give up each and everything as soon as you breathe your last, for nothing of this world can go with you to the Next World. Of course, you will get credit for what you sacrificed for the pleasure and love of Allah, and lout of Islam."
