"The Messenger of Allah (ﷺ) said: 'Allah, the Mighty and Sublime, did not reveal in the Tawrah or the Injil anything like Umm Al-Quran (Al-Fatihah), which is the seven oft-recited, and (Allah said) it is divided between Myself and My slave will have what he asked for.'"
Sunan an-Nasa'i Book 11, Hadith 39
