Shaqayq bin Salmah al-Asadi شقيق بن سلمة الأسدي أبو وائل الكوفي · The Book of Purification

"When the Messenger of Allah (ﷺ) got up at night, he would brush his mouth with the Siwak."

"I was walking with the Messenger of Allah (ﷺ) and he came to some people's garbage dump and urinated while standing up. I turned to go away, but he called me back (to conceal him), and I was just behind him. Then when he had finished, he performed Wudu' and wiped over his Khuffs."

It was narrated from Hudhifah that the Messenger of Allah (ﷺ)came to some people's garbage dump and urinated while standing.

"I heard Abu Wa'il (say) that Hudhaifah said: 'The Messenger of Allah (ﷺ) came to some people's garbage dump and urinated while standing.'"

"And he wiped over his Khuffs," but Mansur did not mention the wiping. Meaning, in this route, since Shu'bah narrated it from both Sulaiman and Mansur.

'Where were you, O Abu Hurairah?' He said: 'O Messenger of Allah, you met us but I was Junub, and I did not want to sit in your presence until I had performed Ghusl.' He said: 'Subhan Allah! The believer is not made impure (Najis).'"

"I heard 'Imran bin Husain (say) that the Prophet (ﷺ) saw a man who was by himself and did not pray with the people. He said: 'O So and so, what kept you from praying with the people?' He said: 'O Messenger of Allah, I have become Junub and there is no water.' He said: 'You should use earth for that will suffice you.'"
