Al-Dahhak bin Qays (may Allah be pleased with him) said the same as what Abu Umamah said. Sayyiduna Abu Umamah (may Allah be pleased with him) also narrates it (through another chain) from one of the Companions (may Allah be pleased with him) of the Prophet (peace and blessings be upon him). By this, the narration of Mutarrif regarding the mention of Surah al-Fatihah is strengthened.
