The Ahl al-Bayt of the noble Prophet Muhammad, peace be upon him and his family, are the perfect examples of humanity. The characters and normative conduct resemble and reflect the character of the Holy Prophet (s). Muslims all over the world acknowledge their nobility and hold them as infallible leaders purified by Allah Himself. As depicted by Nahj al-balagha, they are the strongholds of His commandments, fountainheads of knowledge and wisdom and lofty citadels to defend the religion of Islam.
