[Final Testament/Quran 2:183] O you who believe, fasting is decreed for you, as it was decreed for those before you, that you may attain salvation.
[Final Testament/Quran 2:184] Specific days (are designated for fasting); if one is ill or traveling, an equal number of other days may be substituted. Those who can fast, but with great difficulty, may...
...substitute feeding one poor person for each day of breaking the fast. If one volunteers (more righteous works), it is better. But fasting is the best for you, if you only knew.
[Final Testament/Quran 2:185] "Ramadan is the month during which the Quran was revealed, providing guidance for the people, clear teachings, and the statute book. Those of you who witness this month...
...shall fast therein. Those who are ill or traveling may substitute the same number of other days. GOD wishes for you convenience, not hardship, that you may fulfill your obligations, and to glorify GOD for guiding you, and to express your appreciation."
[Final Testament/Quran 2:187] Permitted for you is sexual intercourse with your wives during the nights of fasting. They are the keepers of your secrets, and you are the keepers of their secrets. God knew that you used to betray your souls, and He has redeemed you, and has...
...pardoned you. Henceforth, you may have intercourse with them, seeking what God has permitted for you. You may eat and drink until the white thread of light becomes distinguishable from the dark thread of night at dawn. Then, you shall...
...fast until sunset. Sexual intercourse is prohibited if you decide to retreat to the masjid (during the last ten days of Ramadan). These are God's laws; you shall not transgress them. God thus clarifies His revelations for the people, that they may attain salvation.
