The Battle of Hunain

After the Conquest of Makkah, some of the fierce and proud powerful tribes did not accept and instead chose to continue hostilities in 630 A.D. 

"And on the Day of Hunain (battle) when you rejoiced at your great number, but it availed you naught." (Quran 9:25)

Muslims: 

- 12,000 soldiers

Later, the Invasion of Tai'f was considered as an extension of the Battle of Hunain, since most enemies of Islam migrated there. It took 10-20 days.
