All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger. {C}{C}
It is not a condition before reading researches or accepting the scientific facts in them, that the one who prepares them must be a pious believer.
Those researches and sciences are not rejected just because the one who prepared them is a non-Muslim or a dissolute person. There is no religious impediment to learn useful matters from non-Muslims and their researches, and benefit from them.
Ibn ‘Abbaas narrated: “After the Battle of Badr, some war prisoners had no money to ransom themselves with, so the Prophet made their ransom to teaching the children of the Ansaar how to write.” [Ahmad; Arna’oot classified it as Hassan]
The researches that are rejected are those which our Sharee’ah proved to be void, or which modern science proved to be void.
Allah knows best.
