Say: 'Have iman in it or do not have iman in it.' Certainly, when it is recited to them, those who were given knowledge before it fall on their faces in prostration, saying, 'Glory be to our Lord! The promise of our Lord is truly fulfilled!'
Weeping, they fall to the ground in prostration, and it increases them in humility.
Say: 'Call on Allah or call on the All-Merciful, whichever you call upon, the Most Beautiful Names are His.' Do not be too loud in your salat or too quiet in it, but try to find a way between the two.
And say: 'Praise be to Allah Who has had no son and Who has no partner in His Kingdom and Who needs no one to protect Him from abasement.' And proclaim His Greatness repeatedly!
(Quran, Al-Isra, 107-111)
