Respect for God , Obedience towards Parents .

This hadith explains that the two biggest major sins in Islam are joining partners with Allah and disobeying one's parents. Joining partners with Allah means believing that there is another god besides Him, which is a form of disbelief and polytheism. Disobeying one's parents means not following their orders or advice, even if it goes against what you want to do. Additionally, this hadith also mentions two other major sins which are false testimony and false speech. These refer to lying about something or saying something bad about someone else without any proof or evidence. It is important for Muslims to remember these four major sins so they can avoid them at all costs and stay away from anything that could lead them towards committing them.
