The Prophet (saw) said, “Avoid that which I forbid you to do and do that which I command you to do to the best of your capacity. Verily the people before you were destroyed only because of their excessive questioning and their disagreement with their Prophets.” (Agreed upon). The above hadith provides a straight forward way and a perfect solution for believers to settle their differences. It creates a perfect framework within which humans can happily live and settle their affairs. It's the lack of this framework of divine guidance that we see as the primary reason for discussion-dead-lock. If humans are the ones who are allowed the make the rules, arguments have no way of reaching a resolution when conflicts arise. Who has the final word? Who gets to decide? Who's judgement is final? Seeking to obey Allah and his messenger is a true blessing that relieves a believer from the agony of differences and conflicts.
