Bedouin attack on Madinah
1. Some Bedouin tribes were incited by the false prophet; Tulaiha, to attack
2. To find an excuse for attacking Madinah, these tribes sent deputations to Abu Bakr (radiyallaho anho), asking for exemption from Zakaat
3. Abu Bakr (radiyallaho anho) told them flatly that he would take Zakat from everyone, even if it were a string to tie a camel
4. Three Bedouin tribes (Banu Abs, Banu Dhubyan and Banu Sulaim) attacked Madinah, under the command of Tulaiha's brother
5. The Madenite army surprised them and the Bedouin tribes were defeated in the Battle of Zul-Qissa
