Selling cassette tapes

Q: I am a young man who likes to participate in Da`wah (calling) to the way of Allah and spreading Din (religion) in every place, amongst all the classes of society, and by all means that I consider appropriate. Thus, I would like to buy a tape recorder to record religious and Qur'anic tapes along with beneficial Islamic lectures and distribute them amongst different groups of people as much as I can. I would also like to get singing-tapes from their owners and return them after recording good materials on them. My question is: Is this a good and appropriate deed that serves the Din or is it something that you do not agree with? It is worth mentioning that I consulted one Shaykh in my country about my plan but he objected to it and considered it inappropriate; what is your opinion? Please answer me and write the answer at the bottom of this sheet of paper. May Allah reward you with the best.

A: It is permissible that you buy a tape recorder which you mentioned in the question provided that you only use it for good purposes. You are to be thanked for recording Islamic tapes and distributing them amongst people. (Part No. 13; Page No. 45)  May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
