Surah 10. Yunus, Ayah 50

Lit., "What [part] thereof might the people lost in sin (al-mujrimun) wish to hasten" - meaning, according to Zamakhshari, that "all of [God's] chastisement is awful and bitter, and should inspire one with the desire to flee therefrom;...and there is nothing in it that ought to make one wish to hasten it". This is an allusion to the incredulous inquiry of the deniers of the truth about the coming of the Last Hour (verse {48} above), as well as to their sarcastic demand that they should be immediately chastised by God in proof of Muhammad's prophetic mission (cf. {6:57-58} and 8:32 , as well as the corresponding notes). - The expression "by night or by day" occurring in the preceding sentence denotes the suddenness and unexpectedness with which doom is bound to encompass the evildoers on the Day of Judgment.

The mockery of Unbelievers will be turned into panic when the wrath of Allah descends on them. It may do so suddenly, by night or by day, when they ]cast expect it. Will they then say of any bit of it: "Let it be hastened"?
