Musannaf Ibn Abi Shaybah

Hazrat Zaid bin Wahb narrates that once I went to a graveyard and sat down beside a wall. In the meantime, a man came and straightened a grave and then sat down next to me. I asked him, "Whose grave is this?" He replied, "This is my brother's grave." I said, "Your brother's?" He said, "He is my Islamic brother." I saw him in a dream at night and I said to him, "O so-and-so, may you remain alive! All praise is due to Allah." He said, "The sentence you have uttered, if I were able to say it, and if I had to give away the whole earth in charity to be able to say it, I would do so." Did you see that when people were burying me, a man stood up and performed two rak'ahs of prayer? If I were able to perform those two rak'ahs, they would be dearer to me than the world and whatever is in it.
