Musnad Ahmad Hadith 3461

The Prophet (ﷺ) said: "My Lord, may He be glorified and exalted, came to me last night in the best image - I think he meant when he was asleep (in a dream) - and said: O Muhammad, do you know what the companions on high (the angels) are debating? I said: No. He put his hand between my shoulders, until I felt its coolness on my chest, and l knew what is in the heavens and what is on earth. Then he said: O Muhammad, do you know what the companions on high (the angels) are debating? I said: Yes, they are debating what washes away sins and the levels in Paradise. He said: What washes away sins and what are the levels in Paradise? I said. Staying in the mosques after the prayers, walking on foot to Jumu’ah prayers, and doing wadoo' properly at times when it is difficult. Whoever does that will live in a good state and die in a good state, and he will be free of sins as on the day his mother bore him. Say O Muhammad, when you pray: O Allah, indeed I ask You for good things and giving up evil things, and love of the poor. And when You decree fitnah for Your slaves, cause me to die without being tested. And the levels in Paradise are giving food, spreading (the greeting of) salam and praying at night when people are asleep.
