Ayat 2:185 of the Quran states that "Ramadan is the month in which was sent down the Quran as a guide to mankind also clear signs for guidance and judgement.." It also states in ayat 97:1 that "We have indeed revealed it, (Al-Quran) in the night of power." The night of power (Laylat al-Qadr), as you all know, occurs during the last ten days of Ramadan.
The Prophet said, "If somebody recited the last two Verses of Surat Al-Baqara at night, that will be sufficient for him."
Narrated Abu Huraira: Allah 's Apostle ordered me to guard the Zakat revenue of Ramadan. Then somebody came to me and started stealing of the foodstuff. I caught him and said, "I will take you to Allah's Apostle!" Then Abu Huraira described the whole narration and said:) That person said (to me), "(Please don't take me to Allah's Apostle and I will tell you a few words by which Allah will benefit you.) When you go to your bed, recite Ayat-al-Kursi, (2.255) for then there will be a guard from Allah who will protect you all night long, and Satan will not be able to come near you till dawn." (When the Prophet heard the story) he said (to me), "He (who came to you at night) told you the truth although he is a liar; and it was Satan."
A man was reciting Surat Al-Kahf and his horse was tied with two ropes beside him. A cloud came down and spread over that man, and it kept on coming closer and closer to him till his horse started jumping (as if afraid of something). When it was morning, the man came to the Prophet, and told him of that experience. The Prophet said, "That was As-Sakina (tranquility) which descended because of (the recitation of) the Qur'an."
Allah's Apostle was traveling on one of his journeys, and 'Umar bin Al-Khattab was traveling along with him at night. 'Umar asked him about something, but Allah's Apostle I did not answer him. He asked again, but he did not answer. He asked for the third time!, but he did not answer. On that, 'Umar said to himself, "May your mother lose you! You have asked Allah's Apostle three times, but he did not answer at all!" Umar said, "So I made my camel go fast till I was ahead of the people, and I was afraid that something might be! revealed about me. After a little while I heard a call maker calling me, I said, 'I was afraid that some Qur'anic Verse might be revealed about me.' So I went to Allah's Apostle and greeted him. He said, 'Tonight there has been revealed to me a Surah which is dearer to me than that on which the sun shines (i.e. the world).' Then he recited: 'Verily! We have given you (O Muhammad I, a manifest victory.' " (Surat al-Fath) No. (48.1).
The Prophet said to his companions, "Is it difficult for any of you to recite one third of the Qur'an in one night?" This suggestion was difficult for them so they said, "Who among us has the power to do so, O Allah's Apostle?" Allah Apostle replied: " Allah (the) One, the Self-Sufficient Master Whom all creatures need.' (Surat Al-Ikhlas 112.1--to the End) is equal to one third of the Qur'an."
Narrated Usaid bin Hudair:
That while he was reciting Surat Al-Baqara (The Cow) at night, and his horse was tied beside him, the horse was suddenly startled and troubled. When he stopped reciting, the horse became quiet, and when he started again, the horse was startled again. Then he stopped reciting and the horse became quiet too. He started reciting again and the horse was startled and troubled once again. Then he stopped reciting and his son, Yahya was beside the horse. He was afraid that the horse might trample on him. When he took the boy away and looked towards the sky, he could not see it. The next morning he informed the Prophet who said, "Recite, O Ibn Hudair! Recite, O Ibn Hudair!" Ibn Hudair replied, "O Allah's Apostle! My son, Yahya was near the horse and I was afraid that it might trample on him, so I looked towards the sky, and went to him. When I looked at the sky, I saw something like a cloud containing what looked like lamps, so I went out in order not to see it." The Prophet said, "Do you know what that was?" Ibn Hudair replied, "No." The Prophet said, "Those were Angels who came near to you for your voice and if you had kept on reciting till dawn, it would have remained there till morning when people would have seen it as it would not have disappear.
