"While the Muslims were in Makkah, they were weak and few in number, never possessing the capability nor the divine permission for Jihad (religious war). After migrating to Madinah, they received the order to fight their enemies in defense, as a verse of Surah Hajj [sura 22 of the Qur’an] proclaims: ‘Permission (to fight) has been granted to those being attacked because they are oppressed [22:39].’ Later on the order came to fight the Infidels (kuffar) even though they do not initiate the aggression."
