It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said on the day of the conquest of Makkah: "After the conquest of Makkah, the command of migration no longer remains, but jihad and intention remain. Therefore, if you are called upon to set out, then set out."
