After Rasulullah safely got away from Makkan plot of assassination, the Makkans felt very humiliated and defeated. The Makkan tribes settled their personal quarrels and differences and became a united force in the desire to destroy the Muslims. The kuffar of Makkah did not let the Muslims live in peace for very long. The steady progress and gaining of strength by the Muslims made the kuffar very uneasy as they feared that their way of life, social and economic leadership was danger.
The kuffar became worried with the new force of Islaam and began planning to crush this force. A group of men under the leadership of Kurz bin Jabir from amongst the kuffar came to Madinah and stole some camels from Muslims. This was the first provocation by the kuffar against the Muslims. Rasulullah asked some Muslims to follow them but the kuffar managed to escape.
In the month of Rajab, seventeen months after Hijrat, Rasulullah sent a party of 12 men under the leadership of Hazrat Abdullah bin Jahash (R.A.) to investigate the movement of the Makkans. This group of Sahaba went up to Nakhla, situated between Taif and Makkah. Here a skirmish took place against a caravan, returning to Makkah, Amr bin Hazrami was killed and two were taken prisoners. This group safely returned to Madinah with the two prisoners and goods taken during the skirmish. Rasulullah was not happy with this situation, as he knew that the kuffar would want to take revenge.
In the second year of Hijrat, a caravan of the kuffar of Makkah, under leadership of Abu Sufyaan, went to Syria. Sensing trouble, on his return he sent a message to Makkah asking for help as he feared an attack from the Muslims. The commander of the kuffar Abu Jahl left Makkah with an army of 1000 men to assist Abu Sufyaan and to confront the Muslims of Madinah.
