Sayyiduna Ali (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) came to him and Sayyidah Fatimah one night and said, "Will you not pray (the Tahajjud) prayer?" I replied, "O Messenger of Allah, our souls are in Allah's control; when He wills, He will awaken us." At this response of ours, the Prophet returned without saying anything, but as he was leaving, I heard him striking his thigh and reciting (this verse from Surah Al-Kahf): "Man is the most quarrelsome of all beings." (Al-Kahf 54)
