His statement, “The Friday prayer consists of two rak'ahs,” is established by explicit textual evidence and consensus.
As for the textual evidence, it is a widely transmitted and well-known matter from the Prophet, peace and blessings be upon him, that he would pray the Friday prayer as only two rak'ahs.
As for consensus, it too is an established consensus in which no Muslim has differed.
This proves that the Friday prayer is an independent prayer: it is neither Zuhr nor a substitute for Zuhr. Whoever claims that it is a shortened Zuhr prayer, or a substitute for it, has strayed far from the truth. Rather, the Friday prayer is an independent prayer with its own conditions and its own distinct manner; this is why it is prayed as two rak'ahs, even while one is resident.
His statement, “It is recommended that the recitation be audible,” indicates one respect in which it differs from the Zuhr prayer: among all the daytime prayers, it is recommended that its recitation be audible. When we consider the prayers in which recitation is audible, we find that they are the prescribed prayers of the night—Maghrib, Isha, and Fajr—as well as prayers marked by a public gathering, even when they are held in the daytime, such as the Friday prayer, the Eid prayer, the eclipse prayer, and the prayer for rain. This is because people gather for them in a general public assembly. Thus, the sunnah regarding the eclipse prayer, for example, is for all the people of the town to pray it together in a single congregational mosque; the same applies to the prayer for rain, the Eid prayer, and the Friday prayer.
The wisdom behind making the recitation audible in these prayers attended by a public gathering is to manifest complete harmony and unity. When the imam recites aloud, his recitation becomes the recitation of all those present, as though it were a symbol of the unity of all the people of the town.
