Narrated 'Aisha the wife of the Prophet:
Allah's Apostle called the salamander a bad animal, but I did not hear him ordering it to be killed."
Narrated Aisha (mother of the faithful believers):
I said, "O Allah's Apostle! Shouldn't we participate in Holy battles and Jihad along with you?" He replied, "The best and the most superior Jihad (for women) is Hajj which is accepted by Allah." 'Aisha added: Ever since I heard that from Allah's Apostle I have determined not to miss Hajj.
