(37) باب جَامِعِ مَا جَاءَ فِي الْقُرْآنِ
It was narrated from Abdullah that:
The Prophet (ﷺ) said: "It is not right for any one of you to say: 'I have forgotten such and such a verse.' Rather, he has been caused to forget. Study the Qur'an, for it escapes from the heart of man faster than a camel escapes from its fetter. " (ID)
