Sayyiduna Husayn bin Ali (may Allah be pleased with them both) said that a man came to the Prophet (peace and blessings be upon him) and said: "I am a coward, and I am also weak." So he (peace and blessings be upon him) said: "Come to a jihad in which there is no thorn (no hardship or danger): that is, Hajj."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is not narrated from Sayyiduna Husayn bin Ali (may Allah be pleased with them both) through any chain other than this one."
