Narrated Abu Hurairah: When the Prophet ﷺ went to the privy, I took to him water in a small vessel or a skin, and he cleansed himself. He then wiped his hand on the ground. I then took to him another vessel and he performed ablution. Abu Dawud said: The tradition is transmitted by al-Aswad bin Amir is more perfect.

Shaykh Umar Farooq Saeedi
Benefits and Issues:
After performing istinja (cleaning oneself after relieving oneself) in unpaved places, it is recommended (mustahabb) to further cleanse the hand by rubbing it on the ground, so that even the slightest trace of odor does not remain. And where soil is not available, soap will serve as its substitute.

50. Commentary:
➊ Sometimes, washing with water does not remove the odor from the hand. By rubbing it on earth, the odor is eliminated, and if there is any greasy impurity, the grease is also removed. Nowadays, this purpose can be achieved by using soap and similar substances; earth is not necessary because the objective is cleanliness and purification.
➋ The status of the private part and the hand is not the same; therefore, special cleansing of the hand is necessary because the hand is also used for eating, drinking, reciting the Qur’an, and for supplications and other acts of worship.
