Surah Al-Kahf, Ayah 7

Do not feel sorry because the Idolators do not believe Allah consoles His Messenger for his sorrow

فَلاَ تَذْهَبْ نَفْسُكَ عَلَيْهِمْ حَسَرَتٍ

(So destroy not yourself in sorrow for them.) 35:8

وَلاَ تَحْزَنْ عَلَيْهِمْ

(And grieve not over them.) 16:127

لَعَلَّكَ بَـخِعٌ نَّفْسَكَ أَلاَّ يَكُونُواْ مُؤْمِنِينَ

(It may be that you are going to kill yourself with grief, that they do not become believers.) 26:3 meaning, maybe you will destroy yourself with your grief over them. Allah says:

فَلَعَلَّكَ بَـخِعٌ نَّفْسَكَ عَلَى ءَاثَـرِهِمْ إِن لَّمْ يُؤْمِنُواْ بِهَـذَا الْحَدِيثِ

(Perhaps, you would kill yourself in grief, over their footsteps, because they believe not in this narration.) meaning the Qur'an.

It was said in verse 7: إِنَّا جَعَلْنَا مَا عَلَى الْأَرْ‌ضِ زِينَةً لَّهَا (Surely, We have made what is on earth an adornment for it) with reference to all living forms, vegetation, mountains, minerals and everything else present on the earth. They are its embellishment. That there are snakes, scorpions, beasts and many harmful and fatal things may lead someone to doubt as to how can they be called 'an adornment for it.' This doubt is unfounded because everything in this world considered harmful, fatal or plain bad may be so in a restricted sense but, in terms of the totality of creation, nothing is bad. Everything, no matter how bad, has been invested with many benefits by Allah Ta’ ala on other counts. The medical use of poisonous and fatal life forms in the interest of human beings is an example. Therefore, things that are considered even bad are not that bad in terms of the function of this entire universe.

The Quran is the corrected edition of previous divine scriptures. In the case of previous scriptures, successive generations made the divine teachings complicated by indulging in hair-splitting. Furthermore, the original teachings were subjected to distortion by means of interpolation, and in this way the very direction of these teachings was deflected. The Quran is free of both these types of human interference. On the one hand, it contains religion in its natural, pure and simple form, and on the other, its direction is unwaveringly towards God, as in fact it should be. Why is it that God has arranged for the revelation of scriptures to the people of the world? The purpose of this is to acquaint them with His divine scheme. God has created man in this world for the purpose of trial. Thereafter, He will take a reckoning of everybody, and according to his deeds, will send him to hell or settle him in the eternal gardens of heaven. God wants everybody to be aware of this before death, so that nobody should have any excuse for wrongdoing. One cause of man’s going astray in this world is his taking someone other than God as his supporter. This deviance is at its worst when someone is believed to be the son of God. All such beliefs are false, because there is nobody on earth or in heaven who wields any power or authority except God.
