God’s messenger asked, “Abul Mundhir (this is Ubayy’s Kunya), do you know which verse of God’s Book that you have is greatest?” I replied, “God and His messenger know best.” He repeated his question and I said, “God, there is no god but He, the Living, the Eternal.” Thereupon he struck me on the breast and said, “May knowledge be pleasant for you, Abul Mundhir!”
An-Nawwās b. Sam'ān said he heard the Prophet say, “On the day of resurrection the Qur’ān and those who acted according to it will be brought with sūra al-Baqara and Āl ‘Imran preceding them* like two black clouds or canopies with light between them, or as though they were two flocks of birds in ranks pleading for the one who recited them.”
* Mirqāt says the pronoun may refer either to the people ahl mentioned, or to the Qur’ān, One may therefore read here either ‘them’ or 'it.'
I had been placed in charge of the zakāt of Ramadān by God’s messenger, and when someone came to me and began to take up handfuls of the food, I seized him and told him I was certainly going to take him before God’s messenger. But when he said, “I am needy, have children dependent on me, and my need is great,” I let him go. In the morning the Prophet asked, “What happened to your prisoner last night, Abū Huraira?” and I replied, “Messenger of God, he complained of great need and of having children dependent on him, so I had pity on him and let him go.” He said, “He lied to you, and he will come back.” I realised that he would return because God’s messenger had told me so, and therefore I lay in wait for him. When he came and began to take up handfuls of the food, I seized him and told him I was certainly going to take him before God's messenger; but when he said, “Let me go, for I am needy with children dependent on me, and I shall not return” I had pity on him and let him go. In the morning God’s messenger asked me, “What has happened to your prisoner, Abū Huraira?” and I replied, “Messenger of God, he complained of great need and of having children dependent on him, so I had pity on him and let him go.” He said, “He has certainly lied to you, and he will come back,” so I lay in wait for him, and when he came and took up handfuls of food I seized him and said, “I am certainly going to take you before God’s messenger, for this is the third time you assert you will not return, and then you do.” He said, “If you let me go I will teach you some words by which God will benefit you. When you go to your bed recite the Throne Verse (Qur’ān 2:255), ‘God, there is no god but He, the Living, the Eternal’ to the end of the verse, for a guardian from God will then remain over you and no devil will come near you till the morning.” I therefore let him go, and in the morning God’s messenger asked me, “What has happened to your prisoner?” I replied, “He asserted that he would teach me some words by which God would benefit me.” He said, “He has certainly told you the truth though he is a great liar. Do you know to whom you have been talking for, three nights?” When I replied that I did not, he said, “That was a devil.”
Abū Umāma said he heard God’s messenger say, “Recite the Qur’ān, for on the day of resurrection it will come as an intercessor for those who recite it. Recite the two shining ones, Baqara and sūra Āl Imrān (Qur’ān, 2 and 3). for on the day of resurrection they will come as two clouds or two shades, or two flocks of birds in ranks* pleading for those who recite them. Recite sūra al-Baqara, for using it produces blessing and abandoning it produces regret, and the slothful are unable to recite it.”
