Mishkat al-Masabih 3 Purification كتاب الطهارة 125

وَعَنْ مُعَاذِ بْنِ جَبَلٍ قَالَ: رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا تَوَضَّأَ مسح وَجهه بِطرف ثَوْبه. رَوَاهُ التِّرْمِذِيّ

Mu’adh b. Jabal said that he saw God’s messenger wiping his face with the hem of his garment when he performed ablution. Tirmidhi transmitted it.
