Human beings go to great lengths to protect and preserve what has been given to them. And out of all the things that we possess, nothing is more valuable than our knowledge of Allah. Allah ﷻ tell us in the Qur’an that, if He wanted to, He could make disappear that which He revealed. Allah ﷻ has ultimate authority over everything, even the knowledge that He allows to reach us. If He decided to remove the blessing of knowledge from us, there is nothing that could stop Him. We should be regularly grateful to Allah ﷻ for the blessing of knowing Him and knowing His deen. And, if we are grateful, Allah ﷻ will increase us.
