Firstly: I apologize for asking such a question, and so that there will be no room for doubt about my intention I will say that I bear witness that there is no god but Allaah and that Muhammad is the Messenger of Allah, and I am completely content with Allah as my Lord, Islam as my religion and Muhammad (peace and blessings of Allah be upon him) as my Prophet.   

I am asking about the Sunnah, because there are many reports of a single hadith. For example, we may find in Saheeh al-Bukhaari a hadith that appears in a form different than that in which it appears in Saheeh Muslim. Why isn't the Sunnah like the Holy Qur'aan? What is the difference between the Sunnah and the Holy Qur'aan? Is the Sunnah part of the Wahy that was revealed to the Messenger (peace and blessings of Allah be upon him) or is it just his words and deeds? Is it one of the characteristics of Prophethood or what?

What is your response to the one who says that so long as the Muslim has an atom’s weight of faith in his heart, he will enter Paradise even if he commits zina during his lifetime?

Salam Alaykum shaykh. I have a friend who have accepted Islam not long ago. He asks if it is allowed for him that his father who is not a Muslim, buys a house With a loan based on ribaa (usury/interest). And then my friend will buy the house from his father by monthly installment, without ribaa (usury/interest)?
