The terms Ghazwat and Saraya literally means a campaign or a movement, it is like a cruise or walk towards a place to make sure there is no trouble and threat. They were of two types: Ghazwat and Saraya. Ghazwat are those in which Prophet Muhammad (peace be upon him) himself participated and Saraya are those in which he did not participate but other Muslims did.
In modern terminology, these are named by people as battles and wars but this is wrong because only few campaigns resulted in battles, yes only few of them.
Total Ghazwat and Saraya are counted to be 82 at their maximum that took place within 8 years from 2 Hijri to 9 Hijri.
The number 82 does not mean that 82 independent missions took place but this include every minor and major missions including those which were part of the same mission, for example Uhud is the name of first day battle and Hamar-ul-asad is the name of second day, in which the enemy was chased, but both are counted. So due to this doubt counting the number of missions is increased.
Muslims did not invade any single tribe or group by themselves, rather all the invasions and missions were in the self-defense, in the answer of the attacks by non-Muslims.
Even if it is assumed that all the 82 campaigns were violence-based battles and all of these were started by Muslims, then the numbers tell the entire story:
- Number of people killed was approximately 1018 in these 82 battles, making average of 12 in a single.
- Imprisoned were 6564 of which 6000 is of a single battle of Hunain, making average of 7 people in 81 battles.
- Out of those 6564 people being captives, 6348 were freed by the Prophet (peace be upon him) due to his mercy and kindness without any condition, 2 were killed based on their previous crimes and remaining 215 are unknown, either they were freed or they accepted Islam and lived with Muslims.
Do these statistics make any sense for a group forcing people to accept Islam in a country like Arab which was at its peak of brutality at that time? If we compare these statistics with other civilizations and wars beings fought in the world in which millions of people were killed brutally then the fair conclusion nothing but that revolution brought by Prophet Muhammad (peace be upon him) was a bloodless and peaceful revolution and a miraculous one too. A point of thinking for the unbelievers.
