The Children of Israel
In the name of God, Most Gracious, Most Merciful.
[17:60]
Behold! We told thee that thy Lord doth encompass mankind round about: We granted the vision which We showed thee, but as a trial for men,- as also the Cursed Tree (mentioned) in the Qur’an: We put terror (and warning) into them, but it only increases their inordinate transgression!


* v.60 : The reference may be to lxxii. 28, probably an earlier Makkan revelation. But the argument is independent of time. This verse falls naturally into three divisions. Warnings and Portents and Signs are sent or not sent according to Allah’s All-Wise Plan of Mercy and Justice, this is in no wise inconsistent with the apparent freedom given to the wicked: because (1) in any case Allah is all round all His creatures, and His delay as a Sign of Mercy in no way diminishes His power; (2) the Visions of Truth vouchsafed to Prophets of Allah are themselves Signs by which they can warn the ungodly; and (3) sometimes it is more merciful to give them time by not immediately bringing the matter to judgment.
* Some Commentators take this as referring to the Mi’raj (xvii. 1) and others to other visions. Such visions are miracles, and become a stumbling block to unbelievers. They are an encouragement to men of faith. Thus they are "a trial for men".
* The tree Zaqqum, a bitter and pungent tree described as growing at the bottom of Hell, a type of all that is disagreeable. See xxxvii. 62-65; xliv. 43-46; and lvi. 52. All these are Suras chronologically carlier than this Sura. The application of the name to a tree of the myrobalan kind in the region of Jericho is, I think, of post-Quranic date. It is a trial for wrong- doers. See xxxvii. 63 and n. 4073.
