If light were destroyed...
If light were destroyed, all sources of energy in the world would be wiped out and death would dominate the whole world of matter. Such is the light of faith in the world of spirituality which is the cause of growth, development and life. In the third sentence, it continues saying: “Nor the shade and the heat” A believer continues to live in peace, security and safety under the shade of his faith, but a disbeliever, because of his infidelity, is in inconvenience and pain.
Ra-qib in Mufrada-t says: “The word /h?aru-r/ means: ‘a hot and blazing wind’, (a drying and fatal wind)”. Zamakhshary in Kashsha-f says: “The term /sumu-m/ is called to some harmful and fatal winds which blow during the day, while the Arabic word /haru-r/ is called to the same winds whether they blow during the day or at might.” Anyhow, how different is this wind and the cold cheerful shade which gives rest to both soul and body?
And finally through the last similitude in the fourth verse, the Qur’a-n says: “Neither are the living and the dead alike. …” The believers are the living ones who usually have effort, endeavour, movement and growth. They are somehow like plants which have leaves, flowers, and fruits; but disbelievers are like pieces of dry wood which have neither greenness nor flower, nor shade, and they are not useful but for burning.
Then, at the end of the verse, the Qur’a-n adds: “… Verily Allah makes whom He pleases hear, …” Allah makes him hear in order that he hears the invitation of the truth heartily and answers the call of the callers of Monotheism.
But the more your cry is loud, and your words are pleasant, and the more your statement is expressive, the dead do not perceive anything from it; and those who have lost their human soul as the result of continuously committing sins and being drowned in bigotry, enmity, injustice, and corruption, certainly are not ready to accept your invitation.
The verse says: “… and you cannot make those hear who are in the graves.” In the fifth verse Allah implicitly says that the Prophet (p.b.u.h.) should not be worried and anxious about the lack of faith in them, his duty was to convey it and to warn them.
The verse says: “You are naught but a Warner.” Two Points: The first is the effects of belief and disbelief: We know that the Qur’a-n considers no importance for the geographical, racial, and classical boundaries which separate groups of human beings from each other.
