🔺Note: Remember, this is not a matter of something being Ḥalāl or Ḥarām, rather it is a matter of whether something invalidates the fast or not. Otherwise, eja

🔺Note: Even though voluntary ejaculation outside intercourse does not invalidate the fast, it still reduces the reward of fasting just like engaging in any other sin. The Prophet ﷺ said: ”Whoever does not give up forged speech and evil actions, Allāh is not in need of him leaving his food and drink (i.e. Allāh will not accept his fast).” [Bukhāri] Similarly, he ﷺ said: “There are people who fast and get nothing from their fast except hunger, and there are those who pray and get nothing from their prayer but a sleepless night.” [Ibn Mājah - graded 'Ṣaḥīḥ' Sheikh Albāni in 'Ṣaḥīḥ Ibn Mājah'] ___ 2⃣- Cupping (Ḥijāmah) Most of the scholars hold the view that this does not invalidate the fast, and this is the stronger opinion. Those who consider this to be an invalidator cite as evidence the statement of the Prophet ﷺ: “The cupper and the one cupped have both broken their fast.” [Aḥmad - authenticated by Sheikh Muqbil in Al-Jāmi’ Aṣ-Ṣaḥīḥ] Counter-arguements: (1) It is authentically reported on the authority of ibn ’Abbās raḍhiyallāhu ’anhu, who said: “The Prophet ﷺ performed Ḥijāmah while fasting.” [Bukhāri] This proves that cupping does not invalidate the fast. (2) Ash-Shāfi'ee mentioned in 'Al-Umm' that the ḥadīth of Shaddād was abrogated by the ḥadīth of Ibn ’Abbās. (3) It was narrated on the authority of Thābit Al-Bunāni raḥimahullāh that Anas ibn Mālik raḍhiyallāhu ’anhu was asked: “Did you (the companions) used to dislike cupping for the fasting person? He said: “No, only if it caused weakness.” [Bukhāri] (4) The ḥadīth of Shaddād should not be taken literally, rather what's intended is, cupping can cause someone to break their fast; it may cause the one who is cupped to break his fast due to the weakness he feels after cupping, and it may cause the cupper to break his fast due to the blood reaching his throat as a result of sucking [*]. This response was given by Al-Baghawi & Al-Khaṭṭābi [*] footnote: They did not have suction pumps at that time, so they had to suck up the blood manually using the mouth (5) Al-Khaṭṭābi said, أفطر can mean to enter, or come close to entering the time of Ifṭār. So perhaps the cupping session occurred just before Maghrib. (6) Rather than choose one over the other, it's possible to combine between the two ḥadīths, as stated by Ash-Shawkāni in An-Nayl. If we do so, we come to the conclusion that, Ḥijāmah does not invalidate the fast, but it is disliked if it causes weakness and fatigue. 🔺Note: This includes all other forms of blood release, such as blood donation, bloodletting, etc. _ 3⃣- Using eye drops does not invalidate the fast, because it does not fall under eating or drinking. Also, the eyes are not an inlet leading to the stomach. Even if after using eye drops, one finds some after-taste in his throat, it still does not invalidate the fast, because it's possible for a person to rub Colocynth on his feet and still find its taste in his mouth & throat; which is why Aṣ-Ṣan’āni raḥimahullāh said, not every taste that is felt in the throat invalidates the fast. [Subul As-Salām,] _ 4⃣- Applying kohl does not invalidate the fast even if one finds the taste in his throat, due to lack of authentic evidence to prove otherwise. _ 5⃣- Using ear drops does not invalidate the fast for the same reasons as eye drops. _ 6⃣- Administering medicine through the rectum does not invalidate the fast because there's no evidence to suggest otherwise. 🔺Note: This includes colonoscopy. __ 7⃣- Inserting a urinary catheter does not invalidate the fast, because it does not come under eating or drinking. ___
