Abdullah bin Abi Qais says: I asked Sayyida Aisha (may Allah be pleased with her), how many witr did the Messenger of Allah (peace and blessings be upon him) pray? She said: Four and three, six and three, ten and three, and he (peace and blessings be upon him) did not pray less than seven or more than thirteen witr, and he never left the two rak'ahs (before Fajr).
