Sahih Muslim Hadith 7518

We set out on an expedition along with Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) until we got down at a spacious valley and Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) went to relieve himself. I followed him with a bucket full of water and Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) looked about and he found no privacy but two trees at the end of the valley and Allah's Messenger (ﷺ) went to one of them and took hold of one of its twigs and said: Be thou under my control by the permission of Allah, and so it came under his control like the camel who has its nosestring in the hand of its rider, and then he came to the second tree and took hold of a twig and said: Be thou under my control with the permission of Allah, and it came under his control, and when he came in the middle of the two trees he joined together the two twigs and said: join with the permission of Allah. Jabir رضی اللہ عنہ said: I was afraid lest Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) should be aware of my nearness and go still farther. And Muhammad bin Abbad has used the word faitab'd and I began to talk to myself. And as I saw, I suddenly found Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) before me and the two trees were separated and each one of them was standing at its place. I saw Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) standing for a short time, nodding his head towards right and left. Isma'il pointed towards the right and left with the help of his head (in order to demonstrate how the Prophet had pointed). Then he (the Holy Prophet) came to me and said: Jabir رضی اللہ عنہ did you see my place where I was standing? I said: Allah's Messenger, yes. He then said: Then you should go to those two trees and cut a twig from each of them and go to that place with them where I was standing and stand there where I was standing and place a twig on the right and a twig on the left. Jabir رضی اللہ عنہ said: I set out and took hold of a stone and broke it and sharpened it and then I came to those trees and cut a twig from each one of them. I then came dragging them until I stood at the place where Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) had been standing and placed a twig on the right and a twig on the left. Then I met him and said: Allah's Messenger, I have done that, but (kindly) explain to me the reason for it. Thereupon he said: I passed by two graves the occupants of which had been undergoing torment. I liked to make intercession for them so that the might be relieved of this tormenty as long as these twigs remain fresh.
