Hadith.1769 - It is narrated from Imam al-Hasan ibn Ali ibn Abi Talib عليه السلام that he said:
"A group of Jews came to the Messenger of Allah
سبحانه وتعالى (peace and blessings be upon him and his family), and the most learned among them asked him about certain matters. Among the questions he asked was: 'Why did Allah
سبحانه وتعالى, the Almighty, prescribe fasting during the day for your community for thirty days, while He prescribed fasting for more than that for other nations?'
The Prophet (peace and blessings be upon him and his family) said: 'When Adam
عليه السلام ate from the tree, the effect of it remained in his stomach for thirty days. Therefore, Allah
سبحانه وتعالى, the Almighty, prescribed for his progeny thirty days of hunger and thirst. And what they eat at night is a favor from Allah
سبحانه وتعالى, the Almighty, upon them. The same was the case with Adam
عليه السلام. Thus, Allah
سبحانه وتعالى prescribed it for my Ummah.'
Then he recited this verse: "Fasting is prescribed for you as it was prescribed for those before you, that you may attain taqwa. [It is for] a fixed number of days." (Surah Al-Baqarah
2:183)
The Jewish man said: 'You have spoken the truth, O Muhammad
صلى الله عليه وعلى آله وسلم. What is the reward for one who fasts them?'
The Prophet (peace and blessings be upon him and his family) replied: 'No believer fasts the Month of Ramadan sincerely, seeking its reward, except that Allah
سبحانه وتعالى, Blessed and Exalted, grants him seven virtues:
1. The first is that the forbidden (haram) in his body melts away.
2. He will draw closer to the mercy of Allah
سبحانه وتعالى, the Almighty.
3. He will have atoned for the sin of his father, Adam
عليه السلام.
4. Allah
سبحانه وتعالى will ease for him the throes of death.
5. He will have security from hunger and thirst on the Day of Resurrection.
6. Allah
سبحانه وتعالى will grant him immunity from the Fire.
7. Allah
سبحانه وتعالى, the Almighty, will feed him from the pure delights of Paradise.'
The Jewish man said: 'You have spoken the truth, O Muhammad
صلى الله عليه وعلى آله وسلم.'"
