Mus'ab bin Sa'd (may Allah have mercy on him) says that some people came to Ibn 'Amir to visit him during his illness and began to praise him. Sayyiduna Ibn 'Umar (may Allah be pleased with them both) said: "I will not deceive you more than they have; I heard the Prophet (peace and blessings of Allah be upon him) say that Allah does not accept charity from stolen spoils of war, nor does He accept prayer without purification."
