How can I get involved in the field of da'wah, and is there an institute or college in London or another country specialized in educating and training female callers to Islam (da'iyat)?

Calling to Allah is an obligation upon every capable person, through every legitimate means. Among its greatest means are knowledge and acting upon it, and seeking knowledge is an obligation. The Muslim woman is charged with this duty alongside the man. It is recommended to contact mosques and Islamic centers and cooperate with them, and to establish religious lessons with righteous sisters, and to focus dawah and education on women, due to the societal rectification that results from it.
