Memorisation by the Companions

The Prophet then declared the revelation and instructed his Companions to memorise it. The case of Ibn Mas'ud, who was the first man to publicly recite the Qur'an in Makka, shows that even in the very early phase of the Islamic umma recital of the revelation from memory was practised by the Companions:

'... the first man to speak the Qur'an loudly in Makka after the apostle was 'Abdullah bin Mas'ud. The Prophet's Companions came together and mentioned that the Quraish had never heard the Qur'an distinctly read to them ... When (Ibn Mas'ud) arrived at the maqAm, he read "In the name of God the Compassionate the Merciful", raising his voice as he did so. "The Com- passionate who taught the Qur'an ..." (55:1) ... They got up and began to hit him in the face; but he continued to read so far as God willed that he should read ...

It is also reported that Abu Bakr used to recite the Qur'an publicly in front of his house in Makka. [Sira Ibn Hisham, The Life of Muhammad]
