The people who pass through hardships (which are not of their own making) or who are troubled for the sake of God, will be amply rewarded by Him in the next world. So far as this world is concerned it is a transitory place; people have not to live here for all the time. If somebody has means available to him which are a source of pleasure for him, it is really nothing for him to feel exalted. Whatever is there in this world – means of comfort or hardships – are to come to an end thereafter there is a life which is eternal. Those who look at some insignificant differences in the constitutions of human life and link it with the sins and shortcomings of another previous life are very much mistaken. They do not try to think over another birth which is linked with the next world where the people who have some defects here or who have put themselves to hardships for the sake of God will be amply rewarded. This world is the place of sowing the seed and to avail the opportunity of attaining to the pleasure of God.
