Hadith 6:137
Ubayd Allah ibn Musa narrated to us, from Uthman ibn al-Aswad, from Mujahid, who said: We were present while we were washing a dead person. He said: "Shake him with a shaking, and do not squeeze him, for you do not know what comes out during the squeezing."
حدثنا عبيد الله بن موسى عن عثمان بن الأسود عن مجاهد قال حضرنا ونحن نغسل ميتا فقال انفضوه نفضا ولا تعصروه فإنكم لا تدرون ما يخرج في العصر
