Except Aisha, as she was sixteen at the time, Muhammad only married widows and divorced women. Aisha bint Abi Bakr is often thought of as the Prophet's favorite wife. She is linked to the Quran's injunctions against slander in Sura 24:11–26, for her involvement in "the affair of the lie slander" ("al-ifk"), in which she was falsely accused of "being with" another man, Safwan ibn al-Mu'attal al-Sulami. She is considered to be the first woman to choose "God and His Prophet" over "the world and its adornment". In Sura 33:28–29, God ordered Muhammad's wives to make a decision as to their preference, after the Prophet was annoyed by the wives' growing desire for material possessions. Aisha is also important to the Sunni sect of Islam.
