Talha bin Abdullah narrates: I performed a funeral prayer behind Abdullah bin Abbas (may Allah be pleased with them), and he recited Surah Al-Fatihah in it and recited it aloud, so much so that we heard his voice. When he completed the prayer, I held his hand and asked him about this. He replied: This is Sunnah and it is the truth.
