Yes, it does, based on compulsory precaution.

You should perform the ghusl of janabah before you can pray, and the fast is not affected.

It has been reported that if one breaks his recommended fasting because of accepting the invitation of his fellow believer, Almighty Allah will give him the reward of fasting that day.

If the intention of fasting was fulfilled, and then he was invited to break the fast, it is recommended to accept the invitation and break the fast.

Fasting is among the obligatory pillars that Islam was built upon. Not performing it is amongst the big sins for which Almighty Allah has threatened to punish with hellfire. However, Almighty Allah has also opened the doors of mercy for his slaves when he said: "Say: O My slaves who have wronged their own selves! Despair not of the mercy of Allah, Who forgives all sins. Lo! He is the Forgiving, the Merciful." (53:39). We ask Almighty Allah to forgive all believers and bless us all.
However, alongside this, it is obligatory to make up for all the fasts missed, as well as undertaking the Kaffara and paying the Fidya, as explained in detailed in the treatise of Islamic laws.

You may drink the water to relieve the pain if it causes hardship, but the fast will become invalid and will need to be made up later. However, there is no kaffara in such a situation.

If the fasting person commits one of the things that invalidates the fast without knowing that it does, his fast is not invalidated.

It is not permitted for the person during the state of i'tikaf to smell fragrance with enjoyment. Based on an obligatory precaution a person during the state of i'tikaf should completely avoid all kinds of fragrance.

One must make up the days that he missed after the current month of Ramadan. Furthermore, a sum of 900 grams of wheat, oat, rice or the like must be given to the needy believers for each missed fast, and it is better to give wheat.

There are three possibilities:
First: If fasting harms the pregnant woman or harms her fetus, then it is prohibited for her to fast, and she should make up the missed days later.
Second: If she is close to delivery, and fasting is a strain for her, she is permitted to break the fast and pay the fidya, and make up for the missed fasts later.
Third: If fasting does not harm the pregnant woman or her fetus, then it is obligatory on her to fast.

As long as the native village was your hometown where you used to live and you did not abandon it – i.e. you still consider it as your home town – then your prayer must be offered in full and you can fast as well while you are staying there.

If the two cities are both your permanent hometowns, then you should fast in both of them. If your hometown was one of them and your connection to the other city is temporary, for a month or two for instance, then you should fast in your hometown and not fast in the other.

The beginning of the month is established by physically seeing the crescent, or by the testimony of two trustworthy witnesses, among other ways. If one was certain that he saw the crescent, then he must consider it the first of the month, in both mentioned cases.

If the crescent was seen in one of the countries of Europe, Asia, Africa or Australia, then the beginning of the month is confirmed in all the countries of the world. However, if it was seen in the continents in North or South America, the month is not confirmed in other continents.

If the new moon has been ascertained through the religiously valid way in any place in the Americas, then one should act upon it in all the regions of the Americas. If the sighting of the new moon has not been established, but there is certainty derived from scientific calculations that the new moon has reached the level where it is possible to be seen by the naked eye, then one should act upon that too. If there is no such certainty, then one should assume that the month is continuing until the completion of thirty days.

Inhaling thick dust does not invalidate the fast.

She should make up the purposefully missed fasts, in addition to paying the kaffara for each day missed on purpose.
She also should make up for the days that she missed when she was sick before the next Ramadan. If she did not make up for them before the next Ramadan when she could have done so then she should make up for those days as well as pay the fidya for each day.
An amount of 900 grams of dates, wheat, floor, rice, lentils and the like for every missed fast must be given to the needy people as fidya for each day.
If she could not make up the missed fasts, she should put in her will that someone should make up for the missed fasts after her death.

If he intended to break the fast by such an act, his fasting is invalidated, whether or not ejaculation took place. He would then have to make it up later as qadha as well as pay the kaffarah. If he did not intend to break the fast, his fasting is not void. In any case, it is prohibited for the individual to masturbate even if it does not end with ejaculation. If one does so, he is required to seek the forgiveness from Allah Almighty and repent to Him.

If he did not know that deliberately staying in the state of Janabah until dawn nullifies the fast, then it is valid.
It is also valid if he did not know that he was in the state of Janabah until after dawn when he realized it.
