Witness is the Daybreak. [As it shines through the deep darkness of the night. So does the Qur'an bring light through the Darkness of Ignorance]

And ten Nights. [Believers have noticed the benevolent transformation the Pilgrimage has undergone. From the first to the tenth of the month of Zilhijjah, they used to indulge in all kind of obscenity. They had departed from the way of Abraham, with Hajj consisting of whistling, clapping, circumambulating the Ka'bah in complete nudity. The sublime purpose of the Pilgrimage had been reduced to senseless rituals and abomination 2:125-127, 2:197]

And the Even and the Odd. [Recall your gambling in those ten nights with the even and odd numbers of arrows and the related numeric superstitions in the society]

And Witness to the truth is the departing of the Night of Ignorance.

Is not all this a solemn evidence for every thinking perso?n?

Have you noted how your Lord dealt with 'Aad? [They had refused to listen to their Prophets on equitable treatment with the poor and violated human rights. 7:65-72]

Those whose capital was Iram, the city of towers and lofty mansions. [Iram were the generation of Iram son of Sam son of Noah. The capital of the tribe of 'Aad bears the same name, Iram, and now lies buried in Al-Ahqaf, the Sand-dunes of Southern Arabia. 46:21]

The like of which (the towers and castles) were never built in other cities. [26:128- 134]

And with Thamud, who carved out rocks for dwellings in the valley. [Wadi-al-Qura. 7:74, 15:82]

And with Pharaoh, lord of the pyramids. [20:43, 38:12, 43:78-79. Zil-awtad = Lord of stakes = A mighty emperor = Owner of many tents with pegs well-dug into the ground = Owner of the Pyramids. God's law is also the law of nature and the rise and fall of nations is fully subject to it]
