Hadiths on Manners of Reading and Memorizing the Qur'an

The 3 hadiths concern the manners of the reader of the Qur'an: «Recite the Qur’an as long as your hearts are harmonious», with the order to move away from it in case of divergence; the reminder addressed to those who set the Book of Allah against itself, as the past communities were ruined when they differed about it; and the method of the first students, who learned ten verses without moving to the next ten before knowing their knowledge and application. Two texts are authentic, one is good.
