How is the hijab worn in Islam? And what are Al-Wala' and Al-Bara'?

Al-Wala' wal-Bara' (Loyalty and Disavowal) is the love for obedient Muslims and believers, and the hatred for disbelievers, their actions, and their beliefs. It also entails loving the disobedient believer to the extent of their obedience and hating them to the extent of their disobedience. Allah Almighty commanded loyalty to believers, saying: "And the believing men and believing women are allies of one another" (Quran 9:71), and forbade loyalty to disbelievers, saying: "Let not believers take disbelievers as allies instead of believers" (Quran 3:28). The Prophet, peace and blessings be upon him, encouraged loving faith and hating disbelief, and clarified that the completion of faith is achieved through love and hatred, and giving and withholding, all for the sake of Allah.
