1.4:

Narrated Sa`id bin Jubair: Ibn `Abbas in the explanation of

the Statement of Allah 'Move not your tongue concerning (the

Qur'an) to make haste therewith (75.16)' said "Allah's Apostle

used to bear the revelation with great trouble and used to

move his lips (quickly) with the Inspiration." Ibn `Abbas

moved his lips saying, "I am moving my lips in front of you as

Allah's Apostle used to move his." Sa`id moved his lips

saying: "I am moving my lips, as I saw Ibn `Abbas moving his."

Ibn `Abbas added, "So Allah revealed 'Move not your tongue

concerning (the Qur'an) to make haste therewith. It is for us

to collect it and to give you (O Muhammad) the ability to

recite it (the Qur'an) (75.16−17)' which means that Allah will

make him (the Prophet ) remember the portion of the Qur'an

which was revealed at that time by heart and recite it. The

Statement of Allah: And 'When we have recited it to you (O

Muhammad through Gabriel) then you follow its (Qur'an)

recital' (75.18) means 'listen to it and be silent.' Then it

is for Us (Allah) to make It clear to you' (75.19) means 'Then

it is (for Allah) to make you recite it (and its meaning will

be clear by itself through your tongue). Afterwards, Allah's

Apostle used to listen to Gabriel whenever he came and after

his departure he used to recite it as Gabriel had recited it."
