Abu Musa Al-Ash'ari (May Allah be pleased with him) reported:
The Prophet ﷺ said, "Read the Qur'an regularly. By the One in Whose Hand Muhammad's soul is, it escapes from memory faster than a camel does from its tying ropes."

[Al-Bukhari and Muslim].

عن أبي موسى رضي الله عنه عن النبي ﷺ قال "تعاهدوا هذا القرآن فوالذي نفس محمد بيده لهو أشد تفلتًا من الإبل في عقلها". ((متفق عله)).
