The Devils Deception by Imam Ibn AL-Jawzi

Chapter Nine: Devil's Deception of the Worshipers in their devotions
knowledge rather than joining in seventy battles.
Al-Mu'ata Ibn 'Imran said: Documenting a single ladith is better,
to me, than praying an entire night.
Now that Iblis has deceived them to put seeking knowledge aside,
he begins to deceive them with regards to the performance of rituals.
[ 9:1 ]
Devil's Deception of them in Matters of
Ablutions (wutfu)
He convinces them to take too long while answering the call of
nature. This is harmful for the liver, a person ought to take reasonable
time when doing so.
Others stand up, walk, cough and raise one leg and lower the other
after answering the call of nature, just to make sure that his bladder
is free from urine. The more he does this, the more urine comes
out. This is because more urine accumulates in the bladder while he
does all of these exercises. All he needs to do is to press his penis
with two Oeft) fingers and slide them to its tip. Then he should rinse
with water.
Iblis convinces others to use too much water. According to the
strictest of schools of thought, it is enough to pour water seven
times after eliminating the impurity itself. As for using rocks; three
are enough.
Those who are not sufficed by that which the religion decreed are
innovators and not followers.
