Idolatrous of Makkah were angry about migration of Muhammad PBUH and their angry increased when they listen that Muslims in Madinah uprising and developing themselves in numbers and economically, it was not bearable by idolatrous of Makkah. So they decided to attack on Madinah to finish Muslims. In Madinah Muslims were also informed accordingly about this future aggression by idolatrous of Makkah, so Muslims also departed from Madina and stayed at Place of Badar known due to a well was dig by a person and named it as Badr.
