The Prophet (peace and blessings of Allah be upon him and his family) learned Surah Al-Baqarah and Al-Imran, because learning them is a blessing and leaving them is regret, and magicians cannot learn them. Surah Al-Baqarah and Al-Imran will come on the Day of Resurrection like two pieces of clouds or two cloaks or two groups of birds spreading their wings, defending their friend and companion, and the Almighty Allah will speak to them. They will say: “O Lord of Lords! This servant of Yours called upon Us, and We made him thirsty during the days and keep him awake at night, and his body was tired.” Allah the Almighty says: “O Quran! How was his obedience to what I commanded him in You, that he should prefer Ali ibn Abi Talib (peace be upon him), the brother of Muhammad, the Messenger of Allah (peace and blessings of Allah be upon him and his family)?” They say: “O Lord of Lords and God of Lords! He loved him and loved his friends and was an enemy to his enemies; whenever he was able, he would show his friendship and whenever he was unable, he would be pious and hide it.” God Almighty says: “So, he acted upon you as I had commanded him and honored you and your orders that I honored him with have been given precedence. O Ali (peace be upon him)! Do you not hear the testimony of the Quran about this friend of yours?” Ali (peace be upon him) says: “O my Lord! Yes, I hear.” God Almighty says: “So suggest to this reciter of the Quran something that will increase his desires many times over, which no one knows except God Almighty.” Ali (peace be upon him) suggests many times over what the reciter of the Quran desires; so it is said: “O Ali (peace be upon him)! I gave him what you suggested.” The Messenger of God (peace be upon him and his family) said: “A crown of honor will be placed on the head of the father and mother of the reciter of the Quran, the light of which will illuminate their path for ten thousand years, and a garment will be draped over their bodies, which if all the good deeds in the world were multiplied by a hundred thousand, would still not be equal to the first thread of this garment. Then the kingship will be given to the right hand of this reciter of the Quran and immortality will be given to his left hand.”
