Acquiring Deeni Knowledge

Q: In order to become a mufti or aalim, must one aalim or mufti teacher must die in order to pass the title for one to become one and give a fatwa?

Q: What is the document in shariah to take fatwa from majority of scholars?

Q: How do you explain to someone that certain things in Islam should not be questioned because he says that things don't make sense to him and certain Ulama are not helpful with questions that he has, although he won't say exactly what these questions are.

Q: When we keep Islamic books, etc. in book shelves, dust accumulates on them with the passage of time. Will we be sinning if we don’t clean the bookshelves and the books of dust?

Q: There is a local mufti or two I'm close with - they are both teachers in madrasah. One of them is a Khatib in a masjid and the other is an imam. They are known for their knowledge and piety. If I get questions pertaining to these should I consult with one of them? I think I'm more comfortable with that as it's easier to express oneself in person. I had previously asked question(s) pertaining to both of them and their answers gave me comfort. Would it be better if I consult one or both of them on this issue and others, especially with regards to my mental state, instead of questioning scholars online for fatwa? Will I be sufficiently fulfilling my responsibility? 

Q: Is it permissible to listen to the bayans of Moulana Tariq Jameel Sb?

Q: I am really in doubt whether hadith is true or not due to many conflicting facts that arised by Ahmed Javed Ghamdi. Now I get thoughts that I am doubting hadith and I can find out whether the hadith is true or not by researching on google which may take time. When I get free time I usually spend on other things. Now I get the thought that i should spend whole my free time in knowing hadith is true or not. Or else i am commiting kufr. This is because if a non muslim can know the truth of islam by researching on google but he doesn't do that knowing that he is able to do. He is ignoring to know truth. I think that i am also doing same case. Feeling scared. Is it kufr if i don't spend my free time in reaserching in google if hadith are true or not?

Q: Is it permissible to listen to Islamic radio stations?

Q: Please give me a link or reference of Quran Majeed app or website with translation and tafseer for mobile.

Q: If someone asks an Aalim any explanation regarding any Islamic issue and the person does not understand, how many times should the Aalim explain the issue? Should he explain it until the person understands it well?
