It is Sunnah for the preacher to raise his voice during the sermon, for whenever the Messenger of Allah ﷺ preached, his voice grew loud and his righteous anger became evident; this strikes the hearts more forcefully and makes the exhortation more effective. He should deliver the sermon in clear, vigorous, and compelling language, phrased with dignified eloquence.
It is also Sunnah that he supplicate for the Muslims, asking for whatever will benefit their religion and their worldly lives, and that he pray for the Muslim ruler and those in authority, beseeching Allah to grant them righteousness and success. Praying for the rulers in the sermon was well known among the early Muslims and was their consistent practice, for supplicating for the Muslim authorities is part of the methodology of Ahl al-Sunnah wa’l-Jamāʿah, whereas leaving it off belongs to the methodology of the innovators. Imam Aḥmad (d. 241 AH) said, “If we had a supplication that we knew would be answered, we would direct it to the ruler,” because his rectitude means the rectitude of the Muslims.
This Sunnah has been so neglected that people now regard praying for those in authority as something odd and suspect anyone who does it.
When the two sermons are finished, it is Sunnah to commence the prayer immediately and to begin without a lengthy pause.
By unanimous agreement, the Friday prayer consists of two rakʿahs in which the recitation is aloud. In the first rakʿah, after al-Fātiḥah, it is Sunnah to recite Sūrah al-Jumuʿah, and in the second, after al-Fātiḥah, Sūrah al-Munāfiqūn, for the Prophet ﷺ used to recite them, as Muslim relates from Ibn ʿAbbās. Alternatively, he may recite in the first rakʿah “sabbiḥ isma rabbika al-aʿlā” (Glorify the name of your Lord, the Most High) and in the second “hal atāka ḥadīth …” (Has there come to you the account of …).
