Ibn Abi Uwais narrated from his father Abu Uwais, and Abu Uwais narrated from Alaa bin Abdur Rahman, who narrated from Abu Hurairah, from the Prophet (ﷺ) a similar hadith, that he said: "Whoever performs a prayer and does not recite Umm al-Qur'an (Surah Al-Fatihah) in it, then this prayer is incomplete, unfinished (and imperfect)."
Imam Tirmidhi says: In the narration of Ismail bin Abi Uwais, nothing more than this is mentioned. I asked Abu Zur’ah about this hadith; he said: Both hadiths are authentic, and he gave evidence from the hadith of Ibn Abi Uwais, which he narrates from his father, and his father from Alaa.
