[Baqarah 2:187] Going to your wives during the nights of the fast is made lawful for you; they are coverings for you and you are coverings for them; Allah knows that you were deceiving yourselves (in this respect), so He accepted your penance and forgave you; so cohabit with them and seek what Allah has destined for you - and eat and drink until the white thread becomes distinct to you from the black thread at dawn - then complete the fast till nightfall; and do not touch women while staying in seclusion for worship in the Masjid; these are the limits imposed by Allah, so do not go near them; this is how Allah explains His verses to mankind so that they may attain piety.
[Qadr 97:3] The Night of Destiny is better than a thousand months.
[Baqarah 2:184] For a certain number of days only; so whoever is sick among you, or on a journey, the same number in other days; and those who do not have the strength for it must give a redemption by feeding a needy person; so whoever increases the good of his own accord, it is better for him; and fasting is better for you, if only you realise.
[Baqarah 2:185] The month of Ramadan in which was sent down the Qur’an - the guidance for mankind, the direction and the clear criteria (to judge between right and wrong); so whoever among you witnesses this month, must fast for the (whole) month; and whoever is sick or on a journey, may fast the same number in other days; Allah desires ease for you and does not desire hardship for you - so that you complete the count (of fasts), and glorify Allah’s greatness for having guided you, and so that you may be grateful.
[A/I`mran 3:133] And rush towards forgiveness from your Lord, and towards a Paradise that can hold all the heavens and the earth in its width - prepared for the pious.
[Hud 11:90] "Ask forgiveness from your Lord and then incline towards Him in repentance; indeed my Lord is Most Merciful, Most Affectionate."
[Tehreem 66:8] O People who Believe! Incline towards Allah in a repentance that becomes a guidance for the future; it is likely that your Lord will relieve you of your sins and admit you into Gardens beneath which rivers flow - on the day when Allah will not humble the Prophet and the believers along with him; their light will be running ahead of them and on their right; they will say, “Our Lord! Perfect our light for us, and forgive us; indeed You are Able to do all things.”
[Hud 11:52] "And O my people! Seek forgiveness from your Lord, then incline towards Him in repentance - He will send abundant rain from the sky upon you and will give you much more strength than you have - and do not turn away committing crimes!"
[Ahzab 33:35] Indeed the Muslim men and Muslim women, and the believing men and the believing women, and the men who obey and the women who obey, and the truthful men and the truthful women, and the patient men and the patient women, and the humble men and the humble women, and charitable men and the charitable women, and the fasting men and the fasting women, and the men who guard their chastity and the women who guard their chastity, and the men who profusely remember Allah and the women who profusely remember Allah – for all of them, Allah has kept prepared forgiveness and an immense reward.
[Ibrahim 14:41] "O our Lord! And forgive me, and my parents, and all the Muslims on the day when the account will be established."
[Hud 11:114] And keep the prayer established at the two ends of the day and in some parts of the night; indeed good deeds wipe out the evil deeds; this is an advice to those who heed it.
[Ibrahim 14:40] "O my Lord! Maintain me as one who establishes prayer, and some of my descendants; O our Lord! and accept my prayer."
[Nisa 4:110] And whoever does evil or wrongs his own soul and then seeks forgiveness from Allah, will find Allah Oft Forgiving, Most Merciful.
