I said, "Messenger of Allah, when I see you my soul is at peace and my eyes find delight, so tell me about everything."He said, "Everything was created from water."I said, "Tell me of a deed which, if I take to it, will admit me into Paradise."He said, "Spread the greeting of peace, feed others, maintain ties of kinship, and stand in prayer at night while people sleep, then enter Paradise in peace."
قلت: يا رسول الله! إني إذا رأيتك طابت نفسي وقرت عيني، فأنبئني عن كل شيء. فقال: كل شيء خلق من ماء قال: قلت: أنبتني عن أمر إذا أخذت به دخلت الجنة. قال: أفش السلام، وأطعم الطعام، وصل الأرحام، وقم بالليل والناس نيام، ثم ادخل الجنة بسلام.
Ahmad narrated it (7932), and Ibn Hibban graded it sahih (508), as did Hakim (4/160), all of them through the route of Hammam bin Yahya, from Qatada, from Abu Maymuna, from Abu Hurairah, who said, then he mentioned it. Hakim said, "This is a hadith sahih in its chain of transmission." And it is as he said.
