In Rajjab 9 Hijra 630 Muslims were got informed that Byzantine Empire with help of Christians planned to attack Muslims with 40000 soldiers. All the Muslims as well as allies of Muhammad, received an urgent call to join the campaign. But the Arab's of the desert showed little interest. Many came up with excuses not to participate. Muhammad provided incentives to persuade the Arabs to join, and provided many with gifts. Muhammad PBUH and all his allies with 30000 soldiers marched to Tabouk (Tabuk), but they see Byzantine did not initiate aggression against Muslims. However the army of Muslims was great than past, they never marched with such a great numbers in past.They stayed there for a number of days but they did not come.
