Is it permissible to eat quat and pluck eyebrows in Islam?

Quat is a leaf which people chew, and often you see when they chew this leaf, they have their one cheek bent out.  The scholars of Islam are unanimous that Quat is a form of intoxicant, but it is widespread in some cultures. One may ask where in the Qur’an is it given that it is forbidden to eat quat. Of course, you will not find quat mentioned anywhere in the Qur’an, but you will find the following instruction in the Qur’an:

مَآ ءَاتَٮٰكُمُ ٱلرَّسُولُ فَخُذُوهُ وَمَا نَہَٮٰكُمۡ عَنۡهُ فَٱنتَهُواْ‌ۚ

"And whatever the Messenger has given you - take; and what he has forbidden you - refrain from."[1]

And that is sufficient to say this is Haram by the Qur’an.

An incident occurred in the time of the Prophet (salallaahu alaihi wasallam) when he was with his companions. Abdullah Ibn Mas’ud (radiAllahu anhu) was teaching the community that plucking eyebrows is haram. When the news reached one of the women who was a Hafidhah of the Qur’an, she came to Abdullah Ibn Mas’ud and asked him if the prohibition of plucking the eyebrows is in the Qur’an. He affirmed and quoted the same verse of the Qur’an (59:7).  The Prophet (salallaahu alaihi wasallam) cursed those who plucked eyebrows and who had their eyebrows plucked. This is sufficient to say that this act is Haram in Islam.
