Salam Houriya,
It is actually encouraged to study and spread the knowledge of The Book continuously
[3:79] It is not conceivable that a human being unto whom God had granted revelation, and sound judgment, and prophethood, should thereafter have said unto people, "Worship me beside God"; but rather [did he exhort them], "Become men of God by spreading the knowledge of the divine writ, and by your own deep study [thereof]."
Learning from others is OK as long as we don't follow blindly and verify it
[39:17] And for those who avoid serving evil, and turn to God in repentance, for them are glad tidings. So give the good news to My servants.
[39:18] The ones who listen to what is being said, and then follow the best of it. These are the ones whom God has guided, and these are the ones who possess intelligence.
[17:36] And do not uphold what you have no knowledge of; for the hearing, and eyesight, and mind—all these you are responsible for.
Wassalam,
Ade
