This is based on general legal evidences recommending reading the Quran on the one hand and the numerous legal evidences denoting the special importance of Al-Fatiha for achieving goals, fulfilling needs and facilitating matters on the other.
General evidences from primary texts
The Quran
God the Almighty says, “Those who recite the Book of Allah, establish regular prayers, and spend (in charity) out of what we have provided for them, secretly and openly, hope for a commerce that will never fail” [35: 29].
The Sunnah
Abu Umama Al-Bahli (may God be pleased with him) narrated that the Prophet (peace and blessings be upon him) said: “Read the Quran for verily it will come on the Day of Judgment as an intercessor for its reciters” [Muslim].
It is established in Islamic legal theory that unconditional commands demand their general applicability with regards to people, circumstances, times and places.
This means that, when God the Almighty legislates a matter in a general or unconditional fashion, it must be applied as such; it is not permissible to restrict or specify it in any manner without evidence from Islamic law.
Restricting matters that God the Almighty and His Messenger have left open and capacious leads to innovation in religion.The Prophet’s observance of certain parts of general,
comprehensive rulings or general rulings denoting specificity does not specify what is general or restrict what is unconditional as long as he did not prohibit otherwise.
Legal theorists have explained this through the legal axiom “Abstention is not proof.” This means that the fact that the Prophet (peace and blessings be upon him) refrained from performing certain acts does not prove their prohibition.
