Habib bin Maslamah narrates that he heard Sayyiduna Abu Dharr (may Allah be pleased with him) say that he heard the Messenger of Allah (peace and blessings be upon him) say: "If my Ummah does not commit treachery in the spoils of war, no enemy will ever be able to stand against them." Then Sayyiduna Abu Dharr (may Allah be pleased with him) asked Habib bin Maslamah: "Does the enemy hold out against you even for as long as it takes to milk a goat?" He replied: "Yes, and even for as long as it takes to milk three goats that give abundant milk." At this, Sayyiduna Abu Dharr (may Allah be pleased with him) said: "By the Lord of the Ka'bah! You have committed treachery (in the spoils of war)."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) only with this chain; Baqiyyah is alone in narrating it."
