 In a beautiful Hadith, Al-Imam Al-Sadiq, Al-Islam says, Al-Imam says, when I look at all the knowledge that is out there, only four types of knowledge are the good types, are the beneficial types. To know who your Lord is, to know who your Creator is, how much time do we spend on a daily basis, to know who Allah SWT is. We spend so much time knowing about everything in our society. We spend so much time knowing about, you know, sport teams, about brands, about everything in society, but how much time do we spend knowing Allah SWT? Al-Imam says, know your Lord. Who is your Lord? Because I tell you, the greatest joy that the Ahlul Bayt had is when they came to know Allah SWT. That's why Imam Ali Ibn Abi Talib, Al-Salam, even though he was wounded and the arrow was through his feet and it was paining him, giving him so much pain, but when he would start his Salah and he would come to know Allah SWT, the beauty of knowing Allah distracted him from the pain of the arrow. This is how the Imam of Ahlul Bayt found joy in this life to know Allah SWT. Then, Al-Imam Al-Saidq, Al-Salam, says the second type of knowledge and, know what your Lord did with you. Here comes the role of science. Know how the universe runs. Know the laws of physics, the laws of chemistry, the social sciences, every cell in your body, you as a believer should know what its function is. Because Al-Imam Al-Saidq says, How did Allah create you? Examine your creation. See the wonders of Allah's creation. Unfortunately, the Muslim world has disregarded this aspect today. This is the role of science. Al-Imam Al-Saidq, Al-Salam, in one of his companions, one of his students, Jabir ibn Hayyan, the Imam Al-Salam gave him a lesson in chemistry, 500 pages long, 1400 years ago. 1300 years ago. Can you imagine? The Imam Al-Salam back then in those backward societies, the Imam is spending from his precious time to teach one of his students chemistry. Yes, because it has value in the eyes of Allah, Subhanahu wa Ta'ala. And the third one, What does Allah want from you? This is an important third type of knowledge. What does God want from me? What does God want from me? Allah has created me. He's blessed me. He's given me everything. In return, what does my Lord want from me? What's expected from me? What is my responsibility? We're always concerned about what others want from us, what our society wants from us, what our government wants from us, what my spouse wants from me, what my parents want from me, what my friends want from me. What Allah wants from me. And the fourth type of knowledge وما يخرجك عن دينك And what is it that causes you to exit your religion? What are the red lines? As believers in Allah do we know the red lines? Do we know what causes us to leave our religion, brothers and sisters? What allows us to exit the religion? Do we know? We have no clue. Sometimes it could be a word that I can say, a word that angers Allah subhanahu wa ta'ala and causes me to leave the religion in the eyes of Allah. Am I aware of those red lines? This is the true knowledge that Imam al-Sadiq, a.s., summarizes for us.
