I say, and with God's success: First: What comes out of the two passages: whether it is habitual, like urine, or non-habitual, like gas, or a worm coming out from the front or the back; as His Exalted saying: (Or has one of you come from the place of relieving himself) [An-Nisa: 43], and the place of relieving oneself is a name for the stable part of the earth, so it is borrowed for what comes out to it, and it includes both habitual and non-habitual. Flowing is not a condition for it; because whenever it appears, it is considered to be transferred, thus it is outside. Second: What comes out from other than the two passages, if it is impure, and flows to a place that must be purified, whether in ablution or washing: and flowing is a condition for what comes out from other than the two passages; because under every skin there is blood and moisture, and in what does not flow, it is apparent but not outside, unlike the two passages; because whenever it appears, it is considered to be transferred, thus it is outside. And the impure substances are: like spilled blood, pus - the thick white that is not mixed with blood - and the discharge - which is the thin water of the wound mixed with blood - these invalidate the ablution, while mucus, tears, saliva, and sweat do not invalidate it; due to their purity. Third: Sleeping while lying down, or reclining, or leaning on something, such that if that thing is removed, he would fall: the sleep that is considered an event is: sleeping while lying down - meaning to sleep with one's sides on the ground - or reclining - meaning on one of his thighs - or leaning on something, such that if that thing is removed, he would fall. However, if he sleeps cross-legged, or in a sitting position, or while praying standing, or bowing, or sitting, or prostrating, his ablution is not invalidated; because sleeping in these positions does not reach the ultimate relaxation, unlike the previous forms. And drowsiness is of two types: heavy: meaning he does not hear what is said to him. It is an event in the case of lying down. And light: meaning he hears what is said to him. It is not an event in the case of lying down. Fourth: Immoral contact: which is when a man touches his wife and their bodies touch while naked with the spread of his organ and the contact of the two private parts; because such a thing is a common cause for the discharge of pre-seminal fluid, which is like a certainty, and the rare occurrence is not considered, thus the cause is treated as the effect; and because it is a state of distraction, and if a little comes out, it is wiped away. Fifth: The loud laughter of a praying adult who is awake while bowing and prostrating: and there is no difference whether he is intentional or forgetful, whether he is in ablution or in dry ablution, and the washing does not invalidate the purity. The limit of loud laughter is what is audible to him and his neighbors, whether his teeth appear or not. Sixth: Fainting, insanity, and intoxication: these invalidate the ablution in any state; because they exceed sleep in relaxation, for the sleeper wakes up with attention, while the insane and the fainted do not wake up with attention; and because insanity and fainting have an effect on the loss of worship, unlike sleep, for a little of it is like permanence; and because the analogy is that sleep is an event in all situations, thus it is left by text, and there is no text in these matters, so they remain on the original. Seventh: Vomiting a mouthful: whether it is bile, food, water, or clotted blood, unlike phlegm, which does not invalidate it. Bile: meaning yellow bile, which is one of the four humors, namely: blood, black bile, yellow bile, and phlegm, and clotted blood: in language, it means coagulated blood, as it is one of its meanings, but what is meant here is black and burnt, and it is not blood in reality, and it is a condition that it be a mouthful; because the mouth has the ruling of what is outside so that it does not break the fast by rinsing, and it has the ruling of what is inside so that it does not break the fast by swallowing something from between his teeth like saliva, thus it is not given the ruling of what is outside unless it fills the mouth. The limit of a mouthful is what cannot be controlled except with difficulty, according to the most correct opinion. See: Tabyin al-Haqaiq 1/10, Al-'Inayah 1/48, Fath al-Qadeer 1/50, Al-Ikhtiyar 1/15-16, Al-Bahr al-Ra'iq 1/39, and Allah knows best.
