It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "O people! Offer sacrifices and hope for reward from Allah for their blood, for even though the blood falls on the ground, it falls into the protection and safekeeping of Allah, Mighty and Majestic."
Imam al-Tabarani (may Allah have mercy on him) said: "Only Ibn Ulathah narrated this hadith from Ibn Abi Ghaniyyah (may Allah have mercy on him), and Amr bin al-Husayn is alone in narrating it."
