Musnad Ahmad 1034:9

Jarir narrated to us, from Mansur, from Abu Wa'il, from Hudhayfah, who said: It reached him that Abu Musa used to urinate into a glass bottle and say: "When one of the Children of Israel would get urine on him, he would cut that place." Hudhayfah said: "I wish your companion would not be so strict with this strictness. I saw myself walking with the Messenger of Allah (ﷺ), and we reached a garbage dump. He stood and urinated as one of you urinates. I went to move away from him, but he said: 'Come close.' So I drew near to him until I was at his heels."
