Interestingly sensible, once one has absorbed the basic idea of daytime fasting through Ramadan:
Ruling for person unable to observe fast?
Dr. Ali Ahmed Mashael: If a person is unable to observe fast, he has to feed one poor person for each day that he didn’t fast. But, it is better to observe fast.
What is the ruling on fasting for those who are constantly travelling and not staying at a place for a long time.
Dr. Ali Ahmed Mashael: A traveller is permitted not to fast if he travels over a distance of 78kms per day.
However, a seasoned traveller who does not get travel weary can fast.
If a person stays in the country for four days or more, he should fast and perform prayers.
But if he stays for less than four days, he should perform Jama and Qasr prayers and fast.
Earlier, travelling was not easy. But now travelling has become smooth so fasting is not tough even for regular travellers. So, it is preferable for Muslims to observe fast.
A very sensible observation that the world has changed.
What is the Shariah ruling as regards eye drops and injections during the day?
Dr. Ali Ahmed Mashael: Eye drops, according to Shafai’i and Hanafi, do not break the fast even if the fasting person can taste it in the throat.
This is because the eye is not a normal place for receiving food or drink, even if something reaches the throat.
The fast is broken through anything entering through open ports like the ear, nose and mouth.
Injections do not invalidate the fast, whether it is intravenous or intramuscular, and whether there is a taste or not.
These do not reach the stomach via an open port, unless the injections are used to assist the body as food and drink like in the case of a nutrient injection. In such cases it breaks the fast.
I grew up in a pretty relaxed Catholicism but reading around what the Irish Church of the 50s was like, for example, one can imagine very similar questions and answers about Lent or no meat Fridays and the like. I actually recall one monk teaching us youngsters (and it was youngsters) of a Lenten rule. If we’d given up sweeties for Lent (no, didn’t happen for me but….) did that mean that if we were given some for our birthday, which happened to fall in Lent, we couldn’t eat them? No, your birthday, and for example that of St Patrick if you were of Irish background (and very grudgingly, the Irish influence in British Catholicism being rather strong, St George if you were English, David, Welsh and so on) is a celebratory day, a Feast Day, and thus Lenten restrictions do not apply. That might actually be exactly the same as Shariah works, the answer being dependent upon which authority you consult.
The actual injunctions are different but the method of logic in reaching them is almost exactly the same. I can imagine Rabbis chewing over the same points too, or at least in the same manner.
