I perceive as if I am looking at the Messenger of Allah (ﷺ) folding up a part of his cloth with another one.
Sahih Muslim Book 5, Hadith 67
← Previous Hadith How Is it that someone amongst you stands before his Lord and then spits out in front of Him? Does any one of you like that he should be made to stand in front of someone and then spit at his face? So when any one of you spits, he must spit on his left side under his foot. But if he does not find (space to spit) he should do like this. Qasim (one of the narrators) spat in his cloth and then folded it and rubbed it.

Sahih Muslim Book 5, Hadith 66 Next Hadith → The Messenger of Allah (ﷺ) said: When any one of you is engaged in prayer, he is holding intimate conversation with his Lord, so none of you must spit in front of him, or towards his right side, but towards his left side under his foot.
