He Accumulates Books Without Reading Them
Question :
I have collected many beneficial books, but I haven't read any of them except for a few. Am I sinning for having so many books? Since I lend many of these books to those who do read them, is the level of my wrongdoing diminished?
Answer:
There is no sin upon a Muslim for accumulating books in his personal library and for lending it to those who benefit from them, even if he only reads a small portion of those books. In fact, a person is performing a good deed when he lends his books to trustworthy people who will profit from them, because doing so is a part of promoting good and helping others to increase their level of knowledge, and because Allâh Almighty says:
"Help you one another in righteousness, and piety."
The Prophet ﷺ said:
"Allah helps His servant as long as His servant helps his brother."
