It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him); he said: One day the Messenger of Allah (peace and blessings be upon him) came out to us and said: "I saw in a dream that Jibril was at my head and Mika'il at my feet. One of them said to his companion: 'Strike a parable for him.' So he said: 'Listen, may your ears hear; and understand, may your heart comprehend. The parable of you and your Ummah is like that of a king who built a fortress, then built a house within it, then laid out a banquet there and sent a caller to invite the people to the food. Some of them answered the call of the messenger (the caller), and some of them ignored it. Allah is the King, the fortress is Islam, the house is Paradise, and you, O Muhammad, are the Messenger of Allah. Whoever answers your call enters Islam, whoever enters Islam enters Paradise, and whoever enters Paradise eats of its blessings.'" [Surah Yunus: 25] This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.
