(Verily, there is a chapter in the Qur'an which contains thirty Ayat that will intercede on behalf of its reciter until he is forgiven. (It is): (Blessed be He in Whose Hand is the dominion.)) This Hadith was collected by At-Tirmidhi and the four Sunan Compilers. At-Tirmidhi said concerning it, "This is a Hasan Hadith." At-Tabarani and Al-Hafiz Ad-Diya' Al-Maqdisi both recorded from Anas that the Messenger of Allah ﷺ said,
ارْجِعِ الْبَصَرَ هَلْ تَرَىٰ مِن فُطُورٍ (So, cast your eye again. Do you see any rifts?...67:3). Apparently, this verse shows that it is possible to see the nearest sky with the naked eyes. Sky, in this context, does not necessarily refer to the bluish atmosphere seen over the earth. In fact, the sky may be very much higher than this, and the bluish colour may be that of the upper atmosphere, as claimed by the scientists. This, on the other hand, does not necessarily imply that the sky cannot be seen at all. It is possible that the bluish atmosphere, on account of being transparent, may not block the vision of the actual sky. However, if it is proved by any evidence that the sky cannot be seen with eyes, then the 'casting ones eyes' in this verse would refer to 'intellectual observation'. [ Bayan-ul-Qur’ an ]
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 4–10
A study of the present world reveals a certain contradiction. The whole universe (except for human beings) is running quite perfectly and in the most well-organised manner. It has no defect in it anywhere. On the contrary, one finds many defects in human life. This is because the nature of man’s creation is different. Man in this world is living under testing conditions. A test essentially demands freedom of action. This freedom of action has given the opportunity to human beings to create disturbance and imbalance in the world. The transgression rampant in the human world is the price of human freedom. If such conditions did not exist, how could divine approval be given to those worthy persons who did not transgress, in spite of having opportunities to transgress and who abstained from arrogance in spite of having the power to be arrogant?
