Are the verses and hadiths mentioned concerning the virtue of knowledge exclusive to religious knowledge, or do they include worldly sciences that increase a person's understanding of the Creator and their faith in Him?

The praiseworthy knowledge in the religious texts is the Shar'i (Islamic legal) knowledge, which is the inheritance of the Prophets, as opposed to worldly sciences like medicine and engineering. Nevertheless, beneficial sciences such as medicine are rewarded if the intention is good. Some of them, like medicine, are considered communal obligations (fard kifaya), and their practitioners are rewarded if they intend to benefit Muslims and elevate their standing. Furthermore, contemplating God's creation through these sciences increases faith. Medicine is among the noblest sciences after Shari'a, as it preserves bodies, and its practitioner receives a great reward if his intention is good, because it falls under benevolence, alleviating distress, and benefiting people. "Whoever shows mercy to others, Allah will show mercy to him," and Allah loves those who do good.
