What did Ibn 'Umar say to Al-Hajjaj when asked how he was doing on the day of a forbidden arms ban? (Peace be upon him)
 Narrated Sa`id bin `Amr bin Sa`id bin Al-`Aas:                     Al-Hajjaj went to Ibn `Umar while I was present there. Al-Hajjaj asked Ibn `Umar, "How are you?" Ibn `Umar replied, "I am all right," Al-Hajjaj asked, "Who wounded you?" Ibn `Umar replied, "The person who allowed arms to be carried on the day on which it was forbidden to carry them (he meant Al-Hajjaj)."
