Mura reported from his father, who said, "I was with the Prophet ﷺ on a journey, and he wished to relieve himself. He said to me, 'Go to those two ashaatayn,'" Waki explained that this means small palm trees, "'and tell them that the Messenger of Allah ﷺ commands you both to come together.' So I told them, and they came together, and he screened himself behind them and relieved himself.Then he said to me, 'Go to them and tell each one of them to return to its place.' So I told them, and they returned."
حدثنا علي بن محمد حدثنا وكيع عن الأعمش عن المنهال بن عمرو
بن مرة عن أبيه قال كنت مع النبي ﷺ في سفر فأراد أن يقضي حاجته فقال لي ائت تلك الأشاءتين قال وكيع يعني النخل الصغار فقل لهما إن رسول الله ﷺ يأمركما أن تجتمعا فاجتمعتا فاستتر بهما فقضى حاجته ثم قال لي ائتهما فقل لهما لترجع كل واحدة منكما إلى مكانها فقلت لهما فرجعتا
[Hasan] Ahmad narrated it in 4/170, from Waki, through him.Amash used "an" (indicating a possibly weakened link in the chain), as mentioned before, hadith 178, and Minhal did not hear directly from Yaala, and it contains another defect besides. The hadith has corroborating narrations in Muslim, hadith 3010, and elsewhere.
