It is narrated from Hazrat Saeed that Mus'ab bin Zubair (may Allah be pleased with him) came to Abdullah bin Umar (may Allah be pleased with them both) while he was performing Tawaf between Safa and Marwah. He asked, "Who are you?" He replied, "Your nephew, Mus'ab bin Zubair." He asked, "The governor of Iraq?" He replied, "Yes! I have come to ask you about those people who abandon obedience, shed blood, and seize wealth. Should they be fought against, and if they are overpowered in this, then they fortify themselves and seek amnesty, should they be granted amnesty or should they be killed?" He asked, "How many are they?" He replied, "Five thousand." It is said that upon hearing this, Abdullah bin Umar (may Allah be pleased with them both) said, "Subhan Allah," and said, "O son of Zubair! May Allah prolong your life. If a man were to come to the goats of Zubair (may Allah be pleased with him) and at one time slaughter five thousand of them, would you consider that man to have exceeded the limits?" He replied, "Yes!" He said, "You consider this extravagance in the case of animals who do not know Allah, so how have you come to deem it lawful to kill so many people who recite the Kalimah in a single day?!"
