A Quranic Journal: Surah an-Nasr ayah 2

The Arab tribes were awaiting the settlement of the conflict between Quraish and the Muslims, before accepting Islam, saying: 'If he, Muhammad, prevails over his people, he would indeed be a prophet.' Consequently, when that was accomplished they accepted Islam in large numbers. Not two years were to pass after the conquest of Makka when the whole Arabian Peninsula was dominated by Islam, and, all thanks to Allah, every Arab tribe had declared its belief in Islam.
