“And indeed he fails who corrupts it.
“And indeed he fails who corrupts it.” 'Salvation is Due To 'the Purification of the Carnal Soul' There are some considerable oaths pointed out at the beginning of this Surah. By one consideration, they are eleven oaths, and by another one, they are seven. In any case, in this position the number of oaths is the largest throughout the Qur'an and this shows that in these verses the solemn appeal is made to something very splendid.
The matter is as important as the solemnity of the heavens, Earth, sun, and moon; that which is effective in the fate of Man. First, the oaths will be described and commented on and then, attention will be paid to the great subject that these oaths are made to. "By the Sun and its brightness", As it was mentioned earlier, Qur'anic oaths are generally for two purposes. First, the oaths pertain to the importance of the subject which the oath is made to.
Second, they pertain to the importance of the affairs themselves, since oaths are always made to great matters. In this way, the oaths make Man contemplate and evoke his thoughts to work on the great objects of Allah's sublime creation through which he may find a path to Him.
The sun plays a most important role in Man's life and in the life of all living creatures on the earth, because it is not only a source of heat and energy; the essential factors necessary for life, but also it is the origin of some other life giving factors such as; winds, rains, plants, running rivers and waterfalls, and even the energy mineral sources; oil, coal, and the like, all depend on the sunlight so that if this world- illuminating-lamp ceased one day, darkness, silence and death would dominate everywhere.
The term /duha/ originally means 'those hours of the morning which follow shortly after sunrise', and here it means 'the full brightness of the sun’. The particular emphasis put on the term /duha/ is for its importance, when the glory of sunlight dominates the land. "By the Moon when it follows it (reflects the sun's light)”, This sense, as some commentators have said, refers to the full moon, i.e.
on the fourteenth night of the lunar month; since on this night the moon appears on the eastern horizon nearly at the time of sunset and with its silver light, introduces itself in the sky and to the world when the world is in its most beautiful state to which swearing is done.
