It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that a man came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah, I intend to fight in the way of Allah." He (peace and blessings be upon him) said: "Hold fast to al-Sham (the Levant), then within al-Sham attach yourself to Asqalan; for when the millstone (of tribulations) turns in my Ummah, its people will be in ease and well-being."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ibn Abi Najih (may Allah have mercy on him) except Muhammad bin Ishaq (may Allah have mercy on him), and no one from Muhammad bin Ishaq (may Allah have mercy on him) except Yahya bin Sulayman (may Allah have mercy on him), while Hafs bin Maysarah (may Allah have mercy on him) is alone in narrating it."
