Explanation & Benefits
Hafiz Abdush Shakoor Tirmidhi
Benefits: From the aforementioned hadith, it is understood that prayer can be performed on a small mat, and this hadith also refutes those who claim that it is necessary for the ground to be made of earth for prostration. "Khumrah" refers to a small mat; it can be made of palm leaves or any other material. (Nayl al-Awtar: 2/129)
