question #3 Sahih Muslim 1067, Book 12, Hadith 206 : What does the hadith imply about the importance of sincerity and depth in religious practice?

Verily there would arise from my Ummah after me or soon after me a group (of people) who would recite the Qur’an, but it would not go beyond their throats, and they would pass clean through their religion just as the arrow passes through the prey, and they would never come back to it. They would be the worst among the creation and the creatures. Ibn Samit (one of the narrators) said: I met Rafi’ b. ‘Amr Ghifari, the brother of Al-Hakam Ghifari and I said: What is this hadith that I heard from Abu Dharr, i. e. so and so? and then I narrated that hadith to him and said: I heard it from the Messenger of Allah (ﷺ).
