وَمِنْهُم مَّن يَقُولُ رَبَّنَآ ءَاتِنَا فِى ٱلدُّنْيَا حَسَنَةً وَفِى ٱلْءَاخِرَةِ حَسَنَةً وَقِنَا عَذَابَ ٱلنَّارِ

Prayers, especially those offered during the pilgrimage, are an outward manifestation of an inward state. Whatever one cherishes in one’s heart, one expresses in prayer. One who has set his mind on worldly riches and grandeur will concentrate on little else when he prays to God, whereas one who seeks the next world, with its infinite happiness and blessings, will make this the central theme of his devotions. This prayer on the part of the believer is not a request for worldly riches. Material gain and worldly wealth are only parts of a ‘test paper’. And no one would like to pray to increase the difficulty of his ‘test paper’. This prayer is more like asking God to give him what is best for man in the eyes of God in this world and what is best for man in the eyes of God in the Hereafter. Therefore, the best prayer for man is to say to his Lord, ‘O my God, give me in this world whatever You see is good for this world, and give me in the next life whatever You see is good for that world and save me from eternal doom.’
