عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا بَيْنَ الْمَشْرِقِ وَالْمَغْرِبِ قِبْلَةٌ» . رَوَاهُ التِّرْمِذِيُّ
Translation

He also reported God’s Messenger as saying, “The rewards of my people were placed before me, even [for] a speck of dust a man takes out of the mosque] and the sins of my people were placed before me, and I saw no sin greater than that a man should memorise a sura or verse of the Qur’an, then forget it."** Cf. Al-Qur’an, 20:126.Tirmidhi and Abu Dawud transmitted it.
