How many generations have we destroyed before them! And they cried for mercy but no time was it of escape!
And they marvel that a warner from among themselves hath come to them; and the infidels say, 'This is a sorcerer, a liar;
Maketh he the gods to be but one God? A strange thing forsooth is this!'
And their chiefs took themselves off. 'Go,' said they, 'and cleave steadfastly to your gods. Ye see the thing aimed at.

Another feature of the revelation of this, the middle Meccan period, is the constant assertion of the. inspiration of the Qur'an. It is called the blessed Book, the luminous Book, the honourable

In the one hundred and ninety-second and following verses of this Sura there is a very strong assertion of the fact that Gabriel brought the Book down from heaven: but, as there is a reference to the Jews, this passage is considered by Jalalu'd-Din as-Syuti to belong to the Madina period and so I do not quote it here. In other parts of this Sura, five of the older prophets are represented as saying 'Fear God and obey me;' and the conclusion drawn is that in like manner the Quraish should obey Muhammad, or suffer for their disobedience; and if they disobeyed him then he could, in the name of God, say,

I will not be answerable for your doings. 216.

The fragmentary nature of the revelations was useful, as it enabled the Prophet to meet with a
