Sunan Abi Dawud Book 2, Hadith 441
The Messenger of Allah(ﷺ) one day came out to us while we were reciting the Qur’an. He said: Praise be to Allah. The Book of Allah is one, and among you are the red, and among you are the white and among you are the black. Recite it before there appear people who will recite it and straighten it as an arrow is straightened. They will get their reward for it in this world and will not get it in the Hereafter.
The Messenger of Allah (ﷺ) came to us while we were reciting the Qur'an, and there were among us bedouins and the non-Arabs. He said: Recite, all is well. In the near future there will appear people who will straighten it (the Qur'an) as an arrow is straightened. They will recite it quickly and not slowly (or it means that they will get the reward in this world and not in the Hereafter).
A man came to the Prophet (ﷺ) and said: I cannot memorise anything from the Qur'an: so teach me something which is sufficient for me. He said: Say Glory be to Allah, and praise be to Allah, and there is no god but Allah, and Allah is most great, and there is no might and no strength but in Allah.
:He said: Messenger of Allah, this is for Allah, but what is for me? He said: Say: O Allah have mercy on me, and sustain me, and keep me well, and guide me. When he stood up, he made a sign with his hand (indicating that he had earned a lot).
The Messenger of Allah (ﷺ) said: He filed up his hand with virtues.
