Allah's Apostle said to me, "Recite the whole Qur'an in one month's time." I said, "But I have power (to do more than that)." Allah's Apostle said, "Then finish the recitation of the Qur'an in seven days, and do not finish it in less than this period."

My father got me married to a lady of a noble family, and often used to ask my wife about me, and she used to reply, "What a wonderful man he is! He never comes to my bed, nor has he approached me since he married me." When this state continued for a long period, my father told the story to the Prophet who said to my father, "Let me meet him." Then I met him and he asked me, "How do you fast?" I replied, "I fast daily," He asked, "How long does it take you to finish the recitation of the whole Qur'an?" I replied, "I finish it every night." On that he said, "Fast for three days every month and recite the Qur'an (and finish it) in one month." I said, "But I have power to do more than that." He said, "Then fast for three days per week." I said, "i have the power to do more than that." He said, "Therefore, fast the most superior type of fasting, (that is, the fasting of (prophet) David who used to fast every alternate day; and finish the recitation of the whole Qur'an In seven days." I wish I had accepted the permission of Allah's Apostle as I have become a weak old man. It is said that `Abdullah used to recite one-seventh of the Qur'an during the day-time to some of his family members, for he used to check his memorization of what he would recite at night during the daytime so that it would be easier for him to read at night. And whenever he wanted to gain some strength, he used to give up fasting for some days and count those days to fast for a similar period, for he disliked to leave those things which he used to do during the lifetime of the Prophet.

Sometimes Allah's Apostle would not fast (for so many days) that we thought that he would not fast that month and he sometimes used to fast (for so many days) that we thought he would not leave fasting throughout that month and (as regards his prayer and sleep at night), if you wanted to see him praying at night, you could see him praying and if you wanted to see him sleeping, you could see him sleeping.

Allah's Apostle used to leave fasting in a certain month till we thought that he would not fast in that month, and he used to fast in another month till we thought he would not stop fasting at all in that month. And if one wanted to see him praying at night, one could see him (in that condition), and if one wanted to see him sleeping at night, one could see him (in that condition) too.

I asked Anas about the fasting of the Prophet. He said "Whenever I liked to see the Prophet fasting in any month, I could see that, and whenever I liked to see him not fasting, I could see that too, and if I liked to see him praying in any night, I could see that, and if I liked to see him sleeping, I could see that, too." Anas further said, "I never touched silk or velvet softer than the hand of Allah's Apostle and never smelled musk or perfumed smoke more pleasant than the smell of Allah's Apostle."

The Prophet took an oath that he would not enter upon some of his wives for one month. But when twenty nine days had elapsed, he went to them in the morning or evening. It was said to him, "O Allah's Prophet! You had taken an oath that you would not enter upon them for one month." He replied, "The month can be of twenty nine days."

The Prophet sent us as an army unit of three hundred warriors under the command of Abu 'Ubaida to ambush a caravan of the Quraish. But we were struck with such severe hunger that we ate the Khabt (desert bushes), so our army was called the Army of the Khabt. Then the sea threw a huge fish called Al-`Anbar and we ate of it for half a month and rubbed our bodies with its fat till our bodies became healthy. Then Abu Ubaida took one of its ribs and fixed it over the ground and a rider passed underneath it. There was a man amongst us who slaughtered three camels when hunger became severe, and he slaughtered three more, but after that Abu 'Ubaida forbade him to do so.
