Is it permissible for a person afflicted with polio to copy and sell books he obtains from the internet, benefiting from the verse in Surat An-Nur: "There is no blame upon the blind, nor any blame upon the lame, nor any blame upon the sick, that they eat from what they own, or from what they are entrusted with the keys," considering that this work is a source of income for him, and the books are sold at the cost of printing and an effort fee only, and he has no means of communicating with the copyright holders, knowing that most of the books are by deceased great Muslim scholars, and the websites from which he obtains the books do not stipulate any conditions for downloading, copying, or selling, and the selling prices are very low?

The esteemed Fiqh Councils and Fatwa Committees hold that intellectual property rights are protected, and it is not permissible to infringe upon them. Therefore, it is forbidden to profit from printing and selling books whose copyrights are reserved. One should choose books whose authors have permitted their printing in order to disseminate knowledge.

As for citing the verse: "There is no blame upon the blind, nor is there any blame upon the lame, nor is there any blame upon the sick. And there is no blame upon yourselves if you eat from your [own] houses or the houses of your fathers or the houses of your mothers or the houses of your brothers or the houses of your sisters or the houses of your paternal uncles or the houses of your paternal aunts or the houses of your maternal uncles or the houses of your maternal aunts or [from houses] whose keys you possess or [from the house of] your friend. There is no blame upon you whether you eat together or separately. And when you enter houses, greet one another with a greeting from Allah, blessed and good. Thus does Allah make clear to you the verses that you may understand" (An-Nur: 61), it is out of place. This is because the verse addresses the lifting of blame for eating from specific houses without permission due to kinship, complete disposition, or friendship, and it has no relation to copying or trading books.

The argument of "possessing the keys to the means" — even if it were valid for mere personal use — is not valid for printing and commercial trading.
