a) Making it up:
Whoever breaks the fast deliberately through eating or drinking must make up that fast. This is the position of the majority of scholars. As for the expiation, then it is not wajib upon him. This is the position of the Shafi`is, Hanbalis, Ibn al-Mundhir, al-Nawawi, and the choice of Ibn `Uthaymin.
b) Abstention:
Whoever deliberately breaks his fast through eating or drinking must abstain therefrom for the rest of the day. This is by agreement of the four schools of jurisprudence and the choice of Ibn Hazm.

Whoever eats or drinks out of forgetfulness, then there is nothing upon him, and he completes his fast. This is the position of the majority: Hanafis, Shafi`is, and Hanbalis.
3. Whatever enters the body unintentionally:
Whatever enters the body of the fasting person unintentionally, like dust on the road, does not break his fast. This is the overall summarised position. [801] There is difference over the fly if it reaches the fasting person’s throat. Consensus has been quoted over this by: Ibn al-Mundhir, Ibn Hazm, Ibn Qudamah, al-Nawawi, and al-Kharshi.
4. Ruling of the fasting person swallowing their saliva:
Swallowing one's own saliva does not break one's fast, as long as it does not leave the mouth nor is collected therein. Consensus has been quoted over this by Ibn Hazm.
5. Swallowing what is between the teeth and cannot be spat out:
Whoever swallows what is between his teeth while fasting, and it is so negligible that it cannot be spat out, then his fast is valid. Consensus has been quoted on this by Ibn al-Mundhir.
6. Swallowing what is between the teeth of what could be spat out:
Whoever swallows what is between their teeth while fasting and he could have spat it out, then his fast is broken. This is the position of the Shafi`is, Hanbalis, and a position among Malikis.

The second: It is that he doesn't need to make it up. This is the position of a group of the Salaf, and is the choice of Ibn Taymiyyah, Ibn al-Qayyim, and Ibn `Uthaymin.
11. Eating or drinking when doubting the sun has set:
Whoever ate or drank doubting the sun has set and did not seek clarity after that, or in the case that it hadn't, then he is sinful and must make up the fast in both instances. This is by agreement of the four schools of jurisprudence.
12. Mistakenly having the pre-dawn meal after fajr:
Whoever had the pre-dawn meal after fajr by mistake, believing it is still before time, then realises that fajr had entered, then the scholars have differed over whether he should make up the fast or not according to two views:

Scholars have differed over the one who engages in sexual intercourse, expiates for his sin, then re-engages in sexual intercourse in the same day, whether he should expiate for the other occasions of intercourse or not. This is according to two views:
The first: It is that the first expiation suffices. This is the position of the Malikis, Shafi`is, and the choice of Ibn `Uthaymin. [803] Ibn `Uthaymin said regarding a man who engaged in sexual intercourse after sunrise by fifteen minutes, then he expiated this by freeing a slave, then he once again engaged in intercourse after zuhr: “According to the school’s position, he must expiate once again, since he expiated the first, even if he is not legally fasting, he must nonetheless abstain. According to the second position, he does not need to expiate the second time since he is no longer fasting, though he must still abstain because anyone who breaks his fast without a valid reason, it is haram for him to continue in indulgence.” Al-Sharh al-Mumti` (407/6)
The second: It is that he is obligated to pay another expiation for the second occasion of intercourse if he had expiated the first. This is the position of the Hanafis and the Hanbalis.
7. The one who repeats intercourse over two days or more:
Whoever engages in sexual intercourse over a number of days, he is obligated to pay an expiration for every day he had intercourse, regardless whether he had expiated the first one or not. This is the position of the majority: Malikis, Shafi`is, and Hanbalis.

Tenthly: Cupping for the fasting
Scholars have differed over the one who undergoes cupping while fasting according to two views:
The first: It is that the fast of the one who undergoes cupping does not break his fast. This is the position of the majority: Hanafis, Malikis, and Shafi`is.
The second: It is that it breaks his fast. [806] Based on this position, it is not permissible for the fasting person to donate a lot of blood that will affect him in the same way cupping does. See: Majmu` al-Fatawa Ibn Baz (272/15), al-Sahrh al-Mumti` (351/6), Permanent Committee Verdicts – Second Collection (179/9). This is among the unique positions of the Hanbali school. It is what is held by Ibn Taymiyyah, [807] Ibn Taymiyyah said: “The position that cupping breaks the fast is that of the majority of Hadith scholars, like Ahmad ibn Hanbal, Ishaq ibn Rahawayh, Ibn Khuzaymah, Ibn al-Mundhir, and others.
