He said: So it shall surely be forbidden to them for forty years, they shall wander about in the land, therefore do not grieve for the nation of transgressors.

And We appointed with Musa a time of thirty nights and completed them with ten (more), so the appointed time of his Lord was complete forty nights, and Musa said to his brother Haroun: Take my place among my people, and act well and do not follow the way of the mischief-makers.

Surely the number of months with Allah is twelve months in Allah's ordinance since the day when He created the heavens and the earth, of these four being sacred; that is the right reckoning; therefore be not unjust to yourselves regarding them, and fight the polytheists all together as they fight you all together; and know that Allah is with those who guard (against evil).

Do you not see that Allah knows whatever is in the heavens and whatever is in the earth? Nowhere is there a secret counsel between three persons but He is the fourth of them, nor (between) five but He is the sixth of them, nor less than that nor more but He is with them wheresoever they are; then He will inform them of what they did on the day of resurrection: surely Allah is Cognizant of all things.
