The Angel casts into his (sallallāhu ‘alayhi wa sallam) heart.
The Angel speaks to him (sallallāhu ‘alayhi wa sallam) in human form.
It comes to him as the ringing of a bell and this is the most difficult upon him (sallallāhu ‘alayhi wa sallam).
He (sallallāhu ‘alayhi wa sallam) sees the Angel in his created form.
That which Allah revealed to him (sallallāhu ‘alayhi wa sallam) on the Night of Ascension.
The direct speech of Allah without mediator.
Some added: Allah speaking to him (sallallāhu ‘alayhi wa sallam) without a veil (based on the opinion that he saw his Lord. However, all the Companions are of the position that he did not see Him).
