The Ruling on A Woman Going Out For Dawah By His Daughter Sukaynah

"And remain in your homes, and do not show your adornment like that of the times of Ignorance, and establish the prayer, give the obligatory charity, and obey Alläh and His Messenger. Alläh only wants to remove the impurity (of sin) from O people of the Household and purify you completely. And remember what is recited in your homes from the Verses of Alläh and wisdom. Indeed, Alläh is Ever Subtle, Well Informed." [Surah al-Ahzãb 33:33-34]
