Printing scientific books

The Messenger of God - may God bless him and grant him peace - said (If a person dies, his work comes to an end except for three: ongoing charity, knowledge that is beneficial, or a righteous child who prays for him) Narrated by Muslim in his Sahih, Al-Tirmidhi, Al-Nasa’i, Imam Ahmad, and everyone who contributed to the dissemination of this useful knowledge. He obtains this great reward whether he is an author, a teacher, a publisher of it among the people, a director, or a contributor to its printing, each according to his effort and participation in it. So contribute to printing books, hoping that they will be a light for you in the sight of God
