Musannaf Ibn Abi Shaybah

Ismail al-Hajdari narrates: We went out for a funeral, and Hasan was also present. He saw that people were crowding around the bier. Hasan said: What is the matter with these people? I think that when Satan saw the sense of goodness and reward among the people, he joined them and cast a whisper into their hearts so that they would crowd while carrying the bier, causing harm to others and thus nullifying their reward.
