Sayyiduna Mus'ab bin Sa'd (may Allah be pleased with him) narrates that Sayyiduna Abdullah bin Umar (may Allah be pleased with him) went to visit Sayyiduna Abdullah bin 'Amir when he was ill. Ibn 'Amir said to Ibn Umar (may Allah be pleased with him): "What is the matter, why do you not pray for me?" He replied: "I heard the Messenger of Allah (peace and blessings be upon him) say: Allah Almighty does not accept prayer without ablution, nor does He accept charity from dishonest wealth. And you have been the governor of Basra (and it is possible that there may have been some irregularity from you)."
