Once, a man from Iraq asked Sayyiduna Ibn Umar (may Allah be pleased with them both) about the ruling if a Muhrim kills a fly. Sayyiduna Ibn Umar (may Allah be pleased with them both) replied: "These people of Iraq come to me asking about killing a fly, while the grandson of the Prophet (peace be upon him) was martyred (without anyone asking about it), even though the Prophet (peace be upon him) had said about his two grandsons: 'These two are my sweet basils from this world.'"
