It is derived from the sentence idha nudiya-lis-salat-imin-yaum-il- Jumu'ati of verse 9. Although in this Surah injunctions about the Friday congregational Prayer also have been given, yet "Jumu'ah " is not the title of its subject-matter as a whole, but this name too, like the names of other Surahs, is only a symbolic title.
Period of Revelation
The period of the revelation of the first section (vv. 1-8) is A. H. 7, and probably it was sent down, on the occasion of the conquest of Khaiber or soon after it. Bukhari, Muslim, Tirmidhi, Nasa'i and Ibn Jarir have related on the authority of Hadrat Abu Hurairah that he and other Companions were sitting in the Holy Prophet's assembly when these verses were revealed. About Abu Hurairah it is confirmed historically that he entered Islam after the truce of Hudaibiyah and before the conquest of Khaiber, and Khaiber was conquered, according to Ibn Hisham, in Muharram, and, according to Ibn Sa\`d, in Jamadi al-Awwal, A.H. 7. Thus presumably Allah might have sent down these verses, addressing the Jews, when their last stronghold had fallen to the Muslims, or these might have been revealed when, seeing the fate of Khaiber, all the Jewish settlements of northern Hijaz had surrendered to the Islamic government.
The second section (vv. 9-11) was sent down shortly after the emigration, for the Holy Prophet (upon whom be Allah's peace) had established the Friday congregational Prayer on the 5th day after his arrival at Madinah. The incident that has been referred to in the last verse of this section must have occurred at a time when the people had not yet received full training in the etiquette of religious congregations.
