Why am I finding it difficult to learn and acquire knowledge after a three-month hiatus from seeking knowledge, and then returning to it? And what is the solution?

All praise is due to Allah for your return to seeking knowledge, which is one of the noblest paths to guidance. We advise you to be patient in seeking knowledge and understanding, and know that seeking knowledge is an act of worship.
