Muʿtazilah (Arabic: المعتزلة‎) is an Islamic school of speculative theology that flourished in the cities of Basra and Baghdad, both in present-day Iraq, during the 8th–10th centuries. The adherents of the Mu'tazili school are best known for their having asserted that, because of the perfect unity and eternal nature of Allah, the Qur'an must therefore have been created, as it could not be co-eternal with God. From this premise, the Mu'tazili school of Kalam proceeded to posit that the injunctions of God are accessible to rational thought and inquiry: because knowledge is derived from reason, reason is the "final arbiter" in distinguishing right from wrong. It follows, in Mu'tazili reasoning, that "sacred precedent" is not an effective means of determining what is just, as what is obligatory in religion is only obligatory "by virtue of reason."

The movement emerged in the Umayyad Era, and reached its height in the Abassid period. Scholarship on the movement stagnated for centuries owing to an absence of sympathetic accounts of the movement (and an abundance of hostile accounts) until the latter 20th century, when the 11th century texts of Abd al-Jabbar al-Qadi were unearthed in Yemen.

Zayd ibn ‘Alī (Arabic: زيد بن علي‎, also spelled Zaid; 695-740) was the grandson of Husayn ibn Alī, the grandson of Muhammad. Zayd was born in Medina in 695. His father was the Shī‘ah Imam ‘Alī ibn Husayn "Zayn al-Abidīn". Zayd’s mother of Sindhi origin named Jaydā, who is said to have been presented to his father by the Shī'ī rebel leader al-Mukhtār.

The prophet once looked at Zayd ibn Harithah, cried, and said "The martyr in the sake of Allah, The crucified of my people, The oppressed from my progeny, his name is thus." Then the prophet pointed at Zayd ibn Harithah and said "Come closer to me, your name became more dear to me because it is the same as my dear child (Zaid.)"

Imam Muhammad al-Baqir narrated: "The Holy Prophet put his sacred hand on Husayn bin Ali's back and said: 'O Husayn, it will not be long until a man will be born among your descendants. He will be called Zaid; he will be killed as a martyr. On the day of resurrection, he and his companions will enter heaven, setting their feet on the necks of the people.'"

"A victim of rape every minute somewhere in the world. Why? No one to blame but herself. She displayed her beauty to the entire world...

"Strapless, backless, sleeveless, nothing but satanic skirts, slit skirts, translucent blouses, miniskirts, tight jeans: all this to tease man and appeal to his carnal nature.

"Would you put this sheep that you adore in the middle of hungry wolves? No... It would be devoured. It's the same situation here. You're putting this precious girl in front of lustful, satanic eyes of hungry wolves. What is the consequence? Catastrophic devastation, sexual harassment, perversion, promiscuity.
