Everyone shall taste death. And only on the Day of Resurrection shall you be paid your wages in full. And whoever is removed away from the Fire and admitted to Paradise, he indeed is successful. The life of this world is only the enjoyment of deception (a deceiving thing). (Quran 3:185).
The soul will not die; but the death of the body will give a taste of death to the soul when the soul separates from the body. The soul will then know that this life was but a probation. And seeming inequalities will be adjusted finally on the Day of Judgement.
Longfellow’s Psalm of Life: “All this world’s a fleeting show, For man’s illusion given”. The only Reality will be when we have attained our final goal
“Those are they who have bought the life of this world at the cost of price of the hereafter. Their torment shall not be lightened nor shall they be helped.” (Quran 2:86)
“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.”(Quran 9:38)
The immediate reference is to the expedition to Tabuk (A.H. 9), for which see the Introduction to this Surah. But the lesson is perfectly general. When a call is made on behalf of a great cause, the fortunate ones are those who have the privilege of responding to the call. The unfortunate ones are those who are so engrossed in their parochial affairs that they turn a deaf ear to the appeal. They are suffering from a spiritual disease. The choice is between two courses: will you choose a noble adventure and the glorious privilege of following your spiritual leader, or grovel in the earth for some small worldly gain or for fear of worldly loss? The people who hesitated to follow the call of TabTik were deterred by (1) the heat of the summer, in which the expedition was undertaken on account of the threat to the existence of the little community, and (2) the fear of losing the fruit harvest, which was ripe for gathering.
