Waislamu, wakiwa wachache na wenye silaha duni, waliingia vitani dhidi ya Quraish na kupambana nao kwa ushindi katika vita vyao vya kwanza, vita vya Badr. Matokeo ya ushindi huu yaliwatikisa Quraish kwa nguvu kiasi kwamba karibu wapoteze fahamu zao. Ushindi wa Waislamu dhidi ya wasioamini ulisaidia kuvunja njama zote za Mayahudi, mipango yao na fitina zao ndani ya Madinah, na kwa matokeo ya moja kwa moja baadhi ya Mayahudi walilazimishwa kutia saini mkataba wa amani, na wengine walifukuzwa kutoka Madinah. Nguvu ya Waislamu iliongezeka, lakini Quraish hawakupumzika kamwe na hawakupoteza muda wowote katika kujiandaa kulipiza kisasi. Katika vita vya Uhud, mwaka uliofuata, Quraish waliweza kufanikisha hilo, wakati wapiga mishale wa Kiislamu waliokuwa wakilinda nyuma ya Mujahidina walipokiuka maagizo ya kiongozi wao kwa haraka ya kukusanya nyara za vita. Quraish walifurahi sana, na Waislamu walirejea Madinah wakiwa na huzuni na kushindwa, licha ya ukweli kwamba baada ya vita hivyo walifuatilia adui hadi Hamra' al-Asad (takriban maili nane kutoka Madinah).

The Muslims, outnumbered and badly equipped, entered into warfare against the Quraysh clashing victoriously with them in their first battle, the battle of Badr. The result of this victory shook the Quraysh so violently that they almost lost their senses. The victory of the Muslims over the non-Muslims helped to kill off all the Jewish plots, schemes and civil strife inside Madinah, and as a direct result some Jews were forced to sign a peace treaty and others were expelled from Madinah. The might of the Muslims increased, but the Quraysh never rested and wasted no time in preparing for revenge. In the battle of Uhud, in the next year, the Quraysh managed just that, when the Muslim marksmen guarding the Mujahideen’s rear disobeyed the instructions of the leader in their haste to gather the spoils of war. The Quraysh were overjoyed, and the Muslims returned to Madinah heartbroken and defeated despite the fact that after the battle they gave chase up to Hamra’ al-Asad (about eight miles from Madinah).
