It has been narrated on the authority of Ibn 'Abbas that the Messenger of Allah (ﷺ) said on the day of the Conquest of Mecca
There is no Hijra now, but (only) Jihad (fighting for the cause of Islam) and sincerity of purpose (have great reward) ; when you are asked to set out (on an expedition undertaken for the cause of Islam) you should (readily) do so.
