Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) said: The Prophet (peace and blessings be upon him) was delayed in coming to us for the Fajr prayer, until the sun was about to overtake us. Then he (peace and blessings be upon him) came out and led us in prayer, and he kept his prayer short. Then, having finished (the prayer), he turned his face towards us and said: "Stay in your places; I will tell you what delayed me from you today in this prayer. I prayed during this night of mine as much as Allah willed, then my eyes grew heavy and I fell asleep, and I saw my Lord, the Mighty and Majestic, in the most beautiful and most handsome form. He said: O Muhammad! I said: Here I am, O my Lord! He said: Over what does the Highest Assembly (the exalted company of angels) dispute? I said: I do not know, O my Lord. Then He said: O Muhammad! I said: Here I am, O my Lord! He said: Over what does the Highest Assembly dispute? I said: I do not know. Then He placed His palm between my shoulders, and I felt the coolness of His fingertips in the middle of my chest, and I came to know everything and I saw it. Then He said: O Muhammad! I said: Here I am, O my Lord! He said: Over what does the Highest Assembly dispute? I said: Over the expiations. He said: And what are they? I said: Walking on foot to the Friday prayers, and performing ablution (wudu) thoroughly in the cold; and the ranks. He said: And what are they? I said: Feeding people, speaking gently, and praying at night while people are asleep. He said: Ask. I said: O Allah, I ask You for good deeds, the abandoning of evil deeds, and love of the poor, and that You forgive me and have mercy on me; and when You intend a trial among Your creation, take me to Yourself without my being afflicted by the trial; and I ask You for Your love, the love of whoever loves You, and the love of deeds that bring me closer to Your love."
