Question: What is the ruling on giving lectures in a masjid of a free-mixing university knowing that lecture and the speakers are from the Salafiyeen?
Answer: “If Ahlul Sunnah gather in that place which there is no free-mixing between men and women or some of the laymen or people are present and they listen to them in that place due to its spaciousness, whether in that place or in another space, then it is upon them to give lectures in it as long as their is no free-mixing”
