Al-Baqarah 2:187 احل لكم ليلة الصيام الرفث الى نسايكم هن لباس لكم وانتم لباس لهن علم الله انكم كنتم تختانون انفسكم فتاب عليكم وعفا عنكم فالان باشروهن وابتغوا ما كتب الله لكم وكلوا واشربوا حتى يتبين لكم الخيط الابيض من الخيط الاسود من الفجر ثم اتموا الصيام الى الليل ولا تباشروهن وانتم عاكفون في المساجد تلك حدود الله فلا تقربوها كذالك يبين الله اياته للناس لعلهم يتقون ١٨٧

It has been made permissible for you the night preceding fasting to go to your wives [for sexual relations]. They are a clothing for you and you are a clothing¹ for them. Allāh knows that you used to deceive yourselves,² so He accepted your repentance and forgave you. So now, have relations with them and seek that which Allāh has decreed for you [i.e., offspring]. And eat and drink until the white thread of dawn becomes distinct to you from the black thread [of night]. Then complete the fast until the night [i.e., sunset]. And do not have relations with them as long as you are staying for worship in the mosques. These are the limits [set by] Allāh, so do not approach them. Thus does Allāh make clear His verses [i.e., ordinances] to the people that they may become righteous.

It has been made permissible for you to be intimate with your wives during the nights preceding the fast. Your spouses are a garment¹ for you as you are for them. Allah knows that you were deceiving yourselves.² So He has accepted your repentance and pardoned you. So now you may be intimate with them and seek what Allah has prescribed for you.³ ˹You may˺ eat and drink until you see the light of dawn breaking the darkness of night, then complete the fast until nightfall. Do not be intimate with your spouses while you are meditating in the mosques. These are the limits set by Allah, so do not exceed them. This is how Allah makes His revelations clear to people, so they may become mindful ˹of Him˺.
