It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that on the Night of the Jinn, two men from among them stayed behind and said: "O Messenger of Allah! We will attend the Fajr prayer with you." The Prophet (peace and blessings be upon him) said: "Do you have water with you?" I said: "I have no water with me, but I have a vessel containing nabidh." The Prophet (peace and blessings be upon him) said: "Wholesome dates and purifying water." Then he (peace and blessings be upon him) performed ablution. Isra'il says in his narration: Then he (peace and blessings be upon him) prayed the morning prayer.
