You want me to give a discourse on Islamic teachings, to introduce the best points of Islam to people when you meet them, is that right? And you require a very short answer. So the shortest answer I can give according to the Holy Qur’an is ittaqullaha, fear Allah.
That covers everything. If you go on preaching this, that would suffice because it is the most comprehensive teaching. It covers every aspect of human behavior, whether related to God or related to human beings. Right? I’m sorry.
