Question: What is the ruling of a person entering the washroom and in his pocket is a Mushaf, knowing that it if he places it outside the washroom he will forget it or lose it?
Answer: He is not sinful the one who enters the washroom with a Mushaf in his pocket because it is not uncovered and it is only in his pocket.
And what is the difference between the one who enters the washroom and in his pocket is a Mushaf, and a person who enters the washroom and in his heart is the whole Quran and there is not in his pocket the Quran. So these are intangible issues.
So if a person enters the washroom and the Mushaf is in his pocket, then he is one who venerated the Quran. If it is apparent in terms that it is not venerated, then this is an amusement which is prohibited.
