(سورة يس, Yaseen, Chapter #36, Verse #12)
O ye who believe! what is the matter with you, that, when ye are asked to go forth in the cause of Allah, ye cling heavily to the earth? Do ye prefer the life of this world to the hereafter? But little is the comfort of this life, as compared with the hereafter.
(سورة التوبة, At-Tawba, Chapter #9, Verse #38)
