It is narrated from Abu Nahik that Sayyiduna Abu Darda (may Allah be pleased with him) used to deliver sermons to the people. One day he said that whoever reaches the morning, there is no Witr for him. Upon hearing this, some people went to Sayyida Aisha (may Allah be pleased with her) and informed her of this statement, but she replied: The Messenger of Allah (peace and blessings be upon him) used to perform Witr even after the morning had come.
