Q: Here in France and in several places of the world such as the United States, England, Australia and other countries there is a group calling itself AICP or Ahbash of Lebanon. They are a sect founded by the Ethiopian Abdullah al-Harari, ILIMAN of this group of interesting knowledge.

The problems is that he declares a very large number of Sunni Muslims to be disbelievers, and that even the most gentle people seem suspicious in their eyes. It is complicated because we are really in trouble. They seem to fight the mistaken beliefs of the Salafists but the problem is that many brothers who do not have the mistaken beliefs of the Salafists are disturbed by their takfir on a lot of personalities. Do we have to learn the knowledge of this group or do away? What are your recommendations. We are exhausted seeing every Muslim like suspicious if he doesn't have the beliefs of this group.

Q: Do you have any history books on Islam (be it Stories of the Prophets alayhis salam, or just general history books on Islam)? On top of reading Bahisthi zewar, I'd like to learn more about the history of Islam and stories of the prophets Alayhis salam so I'd like to know the names of a few books that I can read.

Also do you know any authentic books about the life of Prophet Muhammad (peace be upon him)? And books about the Sahabbah radiyallah anhum?

These books can be in Urdu or English but preferably English and length comprehensive books I would prefer.
