Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Jarir that he says: We stopped at the place of Safah, and there we saw a man sleeping in the shade of a tree. The sun was about to reach him. He says: I said to the servant, "Take this leather and shade this man." The narrator says: So he shaded him. Then, when that man woke up, he was Hazrat Salman. The narrator says: I went to him and greeted him with salam. The narrator says: Then Hazrat Salman said, "O Jarir! Adopt humility for the sake of Allah, because whoever adopts humility for the sake of Allah, Allah Almighty will raise him up on the Day of Judgment. O Jarir! Do you know what the darknesses on the Day of Judgment are?" The narrator says: I replied, "I do not know." He (may Allah be pleased with him) said: "People's oppression of each other in the world." Then he (may Allah be pleased with him) took a stick—I did not think he would keep it in his hand—and said: "O Jarir! If you search for a stick like this in Paradise, you will not find it." The narrator says: I asked, "O Abu Abdullah! Where will the date palms and other trees be?" He (may Allah be pleased with him) said: "Their trunks will be of pearls and gold, and there will be fruit on them."
