Ibn Bazz: whoever is involved in this work to benefit the Ummah will be rewarded

You surely know the significant contribution of Islamic recordings in guiding people during our present time. Yet, some evildoers attempt to tarnish the reputations of shaykhs and accuse them of being materialistic and so forth. I hope that Your Honor will clarify this matter so that the facts are clear to people who do not know the truth. 

A: There is no doubt that the focus on recording useful articles, sermons, and beneficial discussions is helpful to the Ummah (Islamic community); thus, whoever is involved in this work to benefit the Ummah will be rewarded. They should seek Allah's pleasure and be patient in this; even if they suffer from what you have mentioned, to pattern themselves after the Messengers (peace be upon them) and the virtuous people preceding them. Moreover, there is no harm in selling such tapes for nominal prices to avoid burdening people, and to be able to use the money earned in accomplishing their mission as well as helping people in acquiring Islamic knowledge and spreading it. 

I recommend 

acquiring and purchasing good tapes and benefiting from them, if they are useful, for not every person can deliver a useful speech that is worth recording. 

So, 

a knowledge seeker should choose the tapes of scholars who are recognized for their knowledge and scrutinize them to insure they are beneficial, then he/she should circulate these tapes to their family, fellow Muslim, and colleagues to hear. In addition to this, they should beware of recording harmful materials that have no benefits.
