Remain united despite differences , Respect for fellow believers , Never resort to violence .

This hadith, narrated by Abdullah b. Umar, conveys the message that taking up arms against fellow Muslims is not permissible and should be avoided at all costs. The Prophet of Allah has made it clear that anyone who takes up arms against other believers is no longer considered a believer themselves and will be excluded from the Muslim community. This hadith serves as a reminder to all believers to remain united and to never resort to violence or aggression towards one another, regardless of any differences in opinion or beliefs they may have. It also serves as a warning for those who would seek to cause harm or division within the Muslim community, reminding them that such actions are strictly forbidden and will not be tolerated by Allah or His Prophet.
