Ibn ‘Abbās said that God's messenger did not know where sūras were to be separated till “In the name of God, the Compassionate, the Merciful,” was sent down.
Buraida reported God’s messenger as saying, “If anyone recites the Qur’ān seeking thereby to get a living from people, he will come on the day of resurrection with his face as a fleshless bone.”
When we were in Hims Ibn Mas’ūd recited sūra Yūsuf (Quran, 12) and a man declared that it was not sent down like that. To this ‘Abdallāh replied, “I swear by God that I recited it in the time of God’s messenger and he told me I had done it well.” While speaking to him he noticed the smell of wine on him, so he said, “Do you drink wine and declare the Book false?” and then gave him the prescribed beating.
‘Imran b. Husain said that when he came upon a story-teller who was reciting the Qur’ān and then asking for payment he first uttered the words, “We belong to God and to Him do we return” and then told that he had heard God’s messenger say, “When anyone recites the Qur’ān, let him ask a reward for it from God, for people will arise who will recite the Qur’ān and ask a reward for it from men.”
