Ibn Abu Nu’aim narrates: I heard Sayyiduna Abdullah bin Umar (may Allah be pleased with them both). A man asked him about something. The narrator named Shu’bah stated that a man asked him about a person in the state of ihram who kills a fly.

The Prophet (peace and blessings be upon him) said: These two (grandsons) are my fragrance in this world.
