Sayyidah Aishah (may Allah be pleased with her) said: I have not seen any person who was quicker in praying Zuhr early than the Messenger of Allah (peace and blessings be upon him). She did not make an exception of her father (Abu Bakr, may Allah be pleased with him) nor of Umar al-Faruq (may Allah be pleased with him).
