وَإِنَّا إِلَىٰ رَبِّنَا لَمُنقَلِبُونَ (and of course, towards our Lord we have to return - 14). These words teach us that every time a man embarks on a journey, he should think of his last arduous journey to the Hereafter also, which one has to undertake in all circumstances; - and the only way to make it easy is to have a vehicle of good deeds.
