﴿ وَقَالَ ٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ وَٱلْإِيمَٰنَ لَقَدْ لَبِثْتُمْ فِى كِتَٰبِ ٱللَّهِ إِلَىٰ يَوْمِ ٱلْبَعْثِ ۖ فَهَٰذَا يَوْمُ ٱلْبَعْثِ وَلَٰكِنَّكُمْ كُنتُمْ لَا تَعْلَمُونَ ﴾

“But those who [in their lifetime] were endowed with knowledge and faith will say: “Indeed, you have been tardy in [accepting as true] what God has revealed, [and you have waited] until the Day of Resurrection: this, then, is the Day of Resurrection: but you - you were determined not to know it!”

When a man is born, he is but a weak child. Then after experiencing the strength of youth, followed by middle age, he again faces the weakness of old age. This means that a man’s strength is not his own. He receives it when it is given to him. It is in the power of the Giver to give when He likes and take away when He likes. In the life of this world, man cares nothing for the Hereafter, because the Day of Judgement appears to be very far away. But, this is only due to his ignorance. When the Day of Judgement arrives, —the stage for the next world—he will feel as if he had lived in the previous world for only a moment.
