Ibn ‘Umar reported God’s messenger as saying, “These hearts become rusty just as iron does when water gets to it.” On being asked what could clear them he replied, “A great amount of remembrance of death and recitation of the Qur’ān.”
‘Uthmān b. ‘ Abdallāh b. Aus ath-Thaqafī, on his grandfather’s authority, reported God’s messenger as saying, “A man’s recitation of the Qur’ān without using a copy of it produces a thousand degrees of reward, but his recitation while using a copy is double that, reaching two thousand degrees.”
Aifa‘ b. ‘Abd al-Kilā‘ī told of a man who asked God’s messenger which sūra of the Qur’ān was greatest and was told that it is “Say, He is God, One.” He asked which verse of the Qur’ān was greatest and was told that it is the Throne Verse, “God, there is no god but He, the Living, he Eternal.” He asked God’s prophet which verse he would like to bring good to him and his people and was told, ‘‘The end of sūra al-Baqara, for it is one of the treasures of God’s mercy from under His Throne which He gave to this people, and there is no good in this world and the next which it does not include.”
‘Ā’isha reported the Prophet as saying, “Reciting the Qur’ān during prayer is more excellent than reciting it at other times, and reciting the Qur’ān at a time other than during prayer is more excellent than extolling God and declaring His greatness. Extolling God is more excellent than sadaqa, sadaqa is more excellent than fasting, and fasting is a protection from hell.”
