Az-Zumar (Arabic: الزمر, ’az-zumar; meaning: "The Troops, The Throngs") is the 39th chapter (surah) of the Qur'an, the central religious text of Islam.

This surah derives its name from the Arabic word zumar (troops) that occurs in verses 71 and 73.

It also hints at emigration for the believers who were suffering great difficulties in worshiping God in their homeland.

The chapter also reminds readers of the other world, where Muslims believe people will see the outcome of their own deeds.

[2][6]According to Turkish writer Ali Ünal: the word "wraps" in this verse is a simile, which alludes both to the earth's being rounded and to differences in the times of sunrise and sunset.
