No necessarily. Why is measuring the length of clothes = using jinns? I learnt this. You just read some ayats of Quran and the length increases or decreases. There are no jinns involved. I never had any jinns to lengthen it or shorten it. Aaliyat is a complete science. Theres a difference between an amil and a raqi. For becoming a raqi you don't need to do anything. Just memorize some ayats and then you can become a raqi. But amaliyat is a complete science. For becoming an amil you need to do strong amals and sit in chillas and none of our ulama have ever said its not allowed. And as for asking the name of the mother, doesnt mean its a magician. How can one claim that if someone asks for the name of the mother then he's a magician?
