A Gentle Reminder for Those Who Doubt Hadith

Assalamu alaikum. Some folks ask, why trust hadith? They say everything should be in the Quran. But brother, the Quran isn’t a biography of our beloved Prophet Muhammad ﷺ. He was human, living a life with family, friends, and daily matters. His companions, may Allah be pleased with them, loved him and followed that command to 'obey the Messenger.' They memorized his words and actions-things that wouldn’t be in the Quran. Like when Abdullah ibn al-Harith said, 'I never saw anyone smile as much as the Messenger of Allah ﷺ.' That’s from a companion who simply noticed and shared it. Also, everything happens by Allah’s will. Not a leaf falls without it. Think of Prophet Isa (AS) and other prophets. Their teachings got changed by people over time. That’s why Allah sent messenger after messenger. But Allah made Prophet Muhammad ﷺ the final messenger, meaning his Shariah remains till the Day of Judgment. The argument that hadith were compiled after 200 years is weak. Are we saying most of the Ummah from then until now, even till Qiyamah, are following something not part of the religion? That would make the last prophet’s role pointless-may Allah forbid! It’s a reminder to reflect. Jazakumullah khair.
