After the deaths of Hazrat Khadija and Abu Talib, it became impossible for the Prophet (S.A.W.W) to stay in Mecca. The Meccans found it easy to kill the Prophet(S A W.W.) Allah instructed the Prophet (S.A.W.W.) to go to Medina in the darkness of the night. The Prophet (S A W.W) left for Medina secretly.
Imam Ali (A.S) was left behind to take the Prophet’s family to Medina.
Having finished all the jobs that had been left to him by the Prophet (S.A.W.W), Imam Ali (AS) started his journey to Medina His caravan was of four women:
Fatima (S. A) (daughter of the Prophet (S.A.W.W)), Fatima (S.A)(Imam Ali’s mother(, Fatima (daughter of Hamza) and Fatima (daughter of Zubair Bin Abdul Muttalib). Thus began the first journey of Bibi Fatima - A journey of 450 kms to Medina.
The way was full of dangers. Her caravan was attacked by a gang of eight people of Mecca at a place called Dhajnan. They had been sent by Quraish of Mecca. They wanted to take them back to Mecca. Imam Ali (A.S) fought with them and drove them away.
The caravan then proceeded to Quba, where the Prophet (S.A.W.W) was waiting for them. From there they went to Medina to start a new life at a new place.
