Musnad Abu Ya'la al-Mawsili 3:240

Narrated to us Khalaf ibn Hisham, narrated to us Abu al-Ahwas, from Abu Ishaq, who said: 'Abd Khayr mentioned from Ali the like of the hadith of Abu Hayyah, except that 'Abd Khayr said: "When he finished his ablution, he would take a handful of the remainder of his ablution water and drink it."
