The Quran On Fasting
“O you who believe! Fasting is prescribed for you as it was prescribed for those before you, that you may become Al-Muttaqun (the pious).
(Fasting) for a fixed number of days, but if any of you is ill or on a journey, the same number (should be made up) from other days. And as for those who can fast with difficulty, ( i.e. an old man, etc.), they have (a choice either to fast or) to feed a poor person (for every day). But whoever does good of his own accord, it is better for him. And that you fast, it is better for you if only you know.” (2:183-84)
“The month of Ramadan in which was revealed the Quran, a guidance for mankind and clear proofs for the guidance and the criterion (between right and wrong). So whoever of you sights (the crescent on the first night of) the month (of Ramadan), he must fast that month, and whoever is ill or on a journey, the same number (of days which one did not fast must be made up) from other days.
Allah intends for you ease, and He does not want to make things difficult for you. (He wants that you) must complete the same number (of days), and that you must magnify Allah for having guided you so that you may be grateful to Him” (2: 185).
“It is made lawful for you to have sexual relations with your wives on the night of the fasts. They are garments for you and you are the same for them. Allah knows that you used to deceive yourselves, so He turned to you and forgave you. So now have sexual relations with them and seek that which Allah has ordained for you, and eat and drink until the white thread (light) of dawn appears to you distinct from the black thread (darkness of night), then complete your fast till the nightfall.
And do not have sexual relations with them (your wives) while you are in Itikaf in the mosques. These are the limits (set) by Allah, so approach them not. Thus does Allah make clear His signs to mankind that they may become Al Muttaqun (the pious)” (2:187).
“Verily! We have sent it (this Quran) down in the night of Al-Qadr.
And what will make you know what the night of Al-Qadr is?
The night of Al-Qadr is better than a thousand months
Therein descend the angels and the Ruh (Gabriel) by Allah’s Permission with all Decrees,
Peace! until the appearance of dawn (97:1-5).
