"Men are overseers over women, by reason of that wherewith Allah hath made one of them excel over another, and by reason of that which they expend of their substance. Wherefore righteous women are obedient, and are watchers in husbands absence by the aid and protection of Allah. And those wives whose refractoriness ye fear, exhort them, and avoid them in beds, and beat them; but if they obey you, seek not a way against them; verily Allah is ever Lofty, Grand." - Quran 4:34 (read more)

He said, "This is the deficiency in her religion." - Sahih Bukhari 1:6:301 (read more)

"Ibn Sinna (Avicenna) was accused of being a Kafir and an atheist because of his statements about the antiquity of the world, his rejection of the Hereafter, and other atheist theories, in addition to his inner legendary ideology. Other scholars stated that Ibn Sinna was an atheist before Sheikh Al-Huwaini did; amongst them is: Al-Ghazali, Ibn Taymiyah, Ibn Al-Qayim, and Al-Dhahabi." - IslamWeb
