Saying ‘Bismillah’

The Prophet (salAllahu alayhi wasalam) said that
it is one of the names of Allah the distance
between it and Allah’s greatest name, is but like
the distance between the black and white of the
eye seen from a close angle.
[Hakim & Dhahabi in The Book of Excellence of
the Qur’an 1/552]
Ibn Abbas (radiAllahu anhu) said, concerning
‘Bismillah’, Allah evolved it for you, and never had
He evolved it unto any community before you.
[Hakim in Al-Mustadrak & Dhahabi in ‘The Book
of Excellence of the Quran 1/551]
