Imam Zuhri says that I heard from Abu Umamah, who narrates from Saeed bin Al-Musayyib, that the Sunnah method of the funeral prayer is that you first recite Surah Al-Fatihah, then send blessings upon the Prophet Muhammad (peace and blessings be upon him), then pray for the deceased until you finish, and this is to be done only once, and then you say the salam in your heart.
