Musannaf Ibn Abi Shaybah 1588 — Using a towel after ablution

Hakim bin Jabir said: My father sent a slave woman of ours to Sayyiduna al-Hasan bin Ali (may Allah be pleased with him). She saw that Sayyiduna al-Hasan bin Ali (may Allah be pleased with him), after performing ablution (wudu), dried off the water with a cloth. This act of his seemed distasteful to that slave woman, and at night she saw in a dream that her liver was coming out of her mouth.
