وَمَا كَانَ لِنَفْسٍ أَن تَمُوتَ إِلَّا بِإِذْنِ ٱللَّهِ كِتَٰبًا مُّؤَجَّلًا ۗ وَمَن يُرِدْ ثَوَابَ ٱلدُّنْيَا نُؤْتِهِ مِنْهَا وَمَن يُرِدْ ثَوَابَ ٱلْءَاخِرَةِ نُؤْتِهِ مِنْهَا ۚ وَسَنَجْزِى ٱلشَّٰكِرِينَ

During the battle of Uhud, a cry was raised that the Messenger had been slain. This news seriously depressed certain Muslims. But the real servants of God are those whose religiosity is not based on a human personality. God requires a religiosity that attaches His servants with all their hearts and souls to the one God. A believer is one who follows Islam for the truth of its principles rather than for the support of some human individual. One who enters the fold of Islam in this way, finds it such a blessing that his spirit overflows with feelings of gratitude to God. He begins to regard the Hereafter, and not this world, as his all in all. Life becomes to him a transient thing, for he knows that he is going to be faced with death at any point of time. He is able to discern the universe as a divine workshop, where each happening takes place at God’s will and where God is both the Giver and the Taker.
