Does the application of ‘Kohl’ or ‘Surma’ nullify the fast?

Dr. Zakir: As far as putting Al Kohl, in our country India it’s called as Surma or a black eye liner,
It’s Sunnah of the Prophet and we get in the Hadith
(Sunan Abu Dawud, Vol. No. 2, Book of Fasting, Hadith 2372) that
“Anas (may Allah be pleased with him) he used to always stay with the Prophet, he used to cook his food also and he used to put this Al Kohl and Prophet never prohibited him even when he put during fasting.”
So this proves that putting Kohl does not break the fast, its permitted and even when you put any eye drops or ear drops, even if the ear drops or eye drops after certain time you can feel the taste in the throat, according to most of the scholars it does not invalidate the fast, because that is not the normal passage of food. And eye drops, these are medicines, they aren’t food and there are time that because you know that.. I being a medical doctor, the ears, the nose and throat, they’re connected, know as E.N.T. … E.N.T Ear, Nose and Throat, so when you put eye drops, even the ear drops, you know nasal drops; there are chances after sometime it may go into the throat and you may feel the taste. If it’s a nasal drop you should throw it out, but ear drops and I drops you feel the taste. According to most of the scholars it does not break the fast, but there are some scholars who say that if it reaches the throat it will nullify the fast. But the right ruling is that because it’s not the normal passage for food and drink, according to most of the scholars it does not nullify the fast. And if someone who’s… has a doubt the best for him is, he delays putting those nasal drops after the sunset, so he’s absolutely safe. But the right ruling is that even if you put a nasal drop or ear drop it does not break the fast.
