I have described at length that he kept the tribe of Quraish in suspense and doubt about his faith. But it does not mean that he was not Mumin. To keep one's faith secret where the interest of religion depends upon that secrecy is very much appreciated in the Qur'an. Allah praises a family member of Firaun who believed in Hadhrat Musa - secretly, and thus used his influence and position to benefit Hadhrat Musa.

Commending it, Allah says : "And said a man who was a believer, from among the people of Pharaoh, who used to conceal his faith ... ." (Qur'an, 40:28). The same was the position of Hadhrat Abu Talib. Question: Some Sunni sheikhs say that when Abu Talib died, the Holy Prophet spread his saliva all over his body so that he may not be put into hell. Is this story correct ? Answer: It is all a pack of lies; there is no trace of such thing even in Sunnis' books.

Question: What was the reason behind Usama's expedition ? Because it is as if the Holy Prophet would encourage Muslims to take a vengeance. Answer: Well, when enemy is bent upon destroying you, you have to fight him. As the Ghassanide Chief with the encouragement of the Roman emperor, wanted to crush Islam, it was necessary to weaken him to protect the Muslims and Islam. So much about your question of vengeance. Now, I better mention one thing which can easily be inferred from this event.

The Holy Prophet was aware that his death was very near; also he understood very well that certain people were not happy with the announcement of Ghadeer Khum. It seems that he wanted to send all those people away from Madina, so that when his death came, these people would not be in Madina to make trouble. We find that all immigrants, including Abu Bakr, Umar, Uthman, etc. etc. were strictly ordered to join the army under Usama.

Ali was told to remain in Madina, while others were cursed if they delayed in joining Usama and all of them delayed. This seems to be the real "reason" behind Usama's expedition. Question: The Holy Prophet is recorded to have said: Treat yourself because there is no sickness without treatment. What sort of treatments should a Muslim use ? Answer: Any medicine which does not contain any Haram thing. Question: Are African medicines not allowed in Islam ?

Answer: I do not understand what you mean by "African medicines". If you mean leaves and roots of trees etc., then it is all right if it cures the sickness.
