No One has been granted Immortality in this World
وَمَا جَعَلْنَا لِبَشَرٍ مِّن قَبْلِكَ
(And We granted not to any human being immortality before you;) means, O Muhammad.
الْخُلْدَ
(immortality) means, in this world. On the contrary,
كُلُّ مَنْ عَلَيْهَا فَانٍ - وَيَبْقَى وَجْهُ رَبِّكَ ذُو الْجَلْـلِ وَالإِكْرَامِ
(Whatsoever is on it (the earth) will perish. And the Face of your Lord full of majesty and honor will remain forever.) 55:26-27.
أَفَإِيْن مِّتَّ
(then if you die) means, O Muhammad,
فَهُمُ الْخَـلِدُونَ
(would they live forever) means, they hope that they will live forever after you, but that will not happen; everything will pass away. So Allah says:
كُلُّ نَفْسٍ ذَآئِقَةُ الْمَوْتِ
(Everyone is going to taste death,)
وَنَبْلُوكُم بِالشَّرِّ وَالْخَيْرِ فِتْنَةً
(and We shall test you with evil and with good by way of trial. ) Meaning, "We shall test you, sometimes with difficulties and sometimes with ease, to see who will give thanks and who will be ungrateful, who will have patience and who will despair." `Ali bin Abi Talhah reported from Ibn `Abbas:
وَنَبْلُوكُم
(and We shall test you) means, We will test you,
بِالشَّرِّ وَالْخَيْرِ فِتْنَةً
(with evil and with good by way of trial.) means, with difficulties and with times of prosperity, with health and sickness, with richness and poverty, with lawful and unlawful, obedience and sin, with guidance and misguidance.
وَإِلَيْنَا تُرْجَعُونَ
(And to Us you will be returned.) means, and We will requite you according to your deeds.

Commentary
وَمَا جَعَلْنَا لِبَشَرٍ مِّن قَبْلِكَ الْخُلْدَ (And We did not assign immortality to any human (even) before you. - 21:34) The preceding verses give a strong and logical rebuttal of the unfounded and exaggerated beliefs of the infidels and polytheists to the effect that Sayyidna Masih and Sayyidna ` Uzair (علیہما السلام) are the associates of God or that Masih and the Angels are God's children. Unable to come up with a satisfactory answer to the rational and logical arguments given by the Qur'an, the infidels of Makkah were in despair and wished for the death of the Holy Prophet ﷺٍ. This has been mentioned in some other verses also, like e.g. نَّتَرَبَّصُ بِهِ رَيْبَ الْمَنُونِ (52:30). In this verse (34) Allah Ta` ala has given two answers to their pitiable wish. One, that even if the Holy Prophet ﷺ died early how would it help them? If they thought that they could use the death of the Holy Prophet ﷺ as an argument against his prophethood, they were very much mistaken, because all the other Prophets (علیہم السلام) whose prophethood they themselves had accepted, also died when their time came. Thus, if the death of their own prophets did not alter their position as prophets, how could the death of the Holy Prophet ﷺ change his position? Secondly, if their purpose in wishing for his early death was only to appease their frustration, then they should have known that death is universal, and everybody has to die sooner or later.
اگر بمرد عدو جأٰے شادمانی نیست کہ زندگانیء مانیز جاودانی نیست
If an enemy dies, it is not to be rejoiced, because our own life is not eternal.
Here some prominent features of the earth have been mentioned which remind man of God in order to make him a grateful servant of God. One of these is the mountain ranges that have risen up on the surface of the earth in order to keep the dense matter beneath the seas well-balanced. Probably this refers to what is known as ‘isostasy’ in modern science. Similarly, it is also a sign of God that the earth is so made that man is able to make roadways sometimes on level plains, and sometimes as passages between mountains and rivers. The roof of the sky, which is our upper atmosphere, is composed in such a way as to prevent certain harmful rays of the sun from affecting us in the form of the ozone layer. The atmosphere also prevents the majority of the continuous shower of meteorites from reaching us. In the same way, there are signs in the moving of the sun and the moon in their orbits without clashing with each other, resulting in the regular occurrence of day and night on the earth. Innumerable such signs are found on the earth. If man examines them in depth, he will be overwhelmed by the realisation of God’s blessings and His powers. But he ignores them. Even after seeing clear events and signs, he continues to turn a deaf ear and a blind eye to them.
