Attending islamic lectures frequently, does this to you. It feeds your soul with the goodness of Islam. It raises your spirit, calms your heart, and fills it with the love of the deen. “So give good tidings to My servants. Who listen to speech and follow the best of it. Those are the ones Allah has guided, and those are people of understanding.” (Quran 39:17-18)
The Messenger of Allah (ﷺ) said, “He who follows a path in quest of knowledge, Allah will make the path of Jannah easy to him. The angels lower their wings over the seeker of knowledge, being pleased with what he does. The inhabitants of the heavens and the earth and even the fish in the depth of the oceans seek forgiveness for him.” (Riyad as-Saliheen)
