Yes! This is a real thing. People actually do spend their days talking about this shit with dead seriousness. I don’t think I can fully express just how bizarre a higher level
fiqh class really is.
“How can you distinguish between period blood and blood that is discharged due to an illness? You must smell it and analyze the color. If it is dark with a foul odor, it is period blood and the woman must refrain from prayer. If not, she must wash the affected area before each prayer…”
“Is it necessary to completely remove all traces of brown after taking a dump? No, it is OK to have some traces so long as there are no pieces. One should not spend too much time trying to remove all traces of brown as this is one of the whispers of satan…”
“What should be done if one wakes up to find semen in his garment but does not remember ejaculating? One should take a full bath as it is unlikely that the semen originated from anyone else but himself (Depends on the circumstances, I guess.
)”
“It is not permissible to urinate in standing water then use it for bathing, but the scholars have differed as to whether or not it is permissible to urinate into a vessel, dump it into standing water, then use the standing water for ritual bathing. The majority say that this is not permissible, but the Thahiriyyah say that it is permissible as there is no clear prohibition against it.”
“Is it permissible to wash using water that has been stored in the skin of a dead dog? The scholars have differed in this matter with more than five opinions. If the dog’s skin has been tanned, then (I don’t remember who) says that it is OK. Another school of thought says that it is permissible, but only if the dog’s skin is turned inside out…etc”
When someone has a degree in Islamic Law, they likely spent a few years memorizing crap like this. All of this is covered in “
Bab at-Tahaarah - The Book of Purification" which the scholars say one must learn before moving on to any other matters, as purification is necessary for prayer.
