Chapter : On the desirability of reciting the quran carefully.
Narated By Abu Lubabah : Ubaydullah ibn Yazid said: AbuLubabah passed by us and we followed him till he entered his house, and we also entered it.
There was a man in a rusty house and in shabby condition. I heard him say: I heard the Apostle of Allah (PBUH) say: He is not one of us who does not chant the Qur’an.
