The issue of mixing between the two genders and its guidelines often generates controversy. It is usually surrounded by intense emotions, which cloud an impartial inquiry into the truth. The danger is that an unbalanced understanding of those guidelines or their application could result in significant risks to the individual and the society alike, whether the deviation is towards improper laxity or excessive strictness. I was delighted to read the manuscript of this book "Principles of men women interaction in Islam", which was carefully penned by Dr. Asif Hirani to address this very intricate subject in a language that suits our youth. Dr. Asif did not shy away from analyzing some of the difficult details, and he did not limit himself to classical discussions. He addressed the pertinent issues in our times such as interactions on social media without departing from the tradition or the traditional methodology. It is hoped that his style of writing will appeal to those in greatest need for a detailed contemporary discussion of this issue. - Shaikh Hatem Al-Haj.
