Islam as a religion, is not a man-made organization. It’s religion of nature that matches man’s fate, and religion that was attached to the origin of mankind.
Prophet Muhammad (SAW) is the best teacher and master of all Muslims, he was sent with the Quran to be a guide that contains knowledge, enlightenment, way, and elaboration.
Allah (SWT) should be primary in Muslims life, and be centre of knowledge. A Muslim shouldn’t have an idea or thought that perhaps makes him to disobey him.
The knowledge that Allah teaches, it’s what the Quran contains, which nothing surpasses. There’s no knowledge that can be compared to it.
The role of the Prophet is a big role in life of Muslim, because he expatiates what Allah says in the Quran, and he also sheds light on Islamic affairs.
The prophet Muhammad is the genuine reason and solid source, which Muslims should tap knowledge from.
Anyone in this life is not to be believed, if the person doesn’t quote from the Quran and Hadith, or doesn’t choose what the great scholars of Islam refer to.
Anyone that speaks, without referring to the Quran and Hadith, shouldn’t be listened to, or shouldn’t be seen as a scholar.
All knowledge should be transmitted from both Quran and Hadith.
The reason why any say or reference anything other than the Quran and Hadith is not relevant in Islam, is that all knowledge due to Allah (SWT) and he sent prophet Muhammad (SAW) to explain the knowledge to mankind.
Humans are created to make mistake and to forget, that’s why the checks and balances of Islam are not entrusted to humans.
It’s only Allah (SWT) that knows better, and can’t forget or make mistake, he’s the owner of Islam.
