Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that I said: O Messenger of Allah! When I visit you, my heart becomes happy and my eyes are cooled. Please tell me about everything. The Prophet (peace and blessings be upon him) said: "Everything has been created from water." I said: Tell me about an act which, if I perform it, I will enter Paradise. The Prophet (peace and blessings be upon him) said: "Spread peace (greetings), feed (others), maintain ties of kinship, and stand in prayer at night (tahajjud) while people are sleeping, and you will enter Paradise in peace."
