Al-Kāfi - Volume 6 > Using a Towel to Wipe one’s Face after Wudu (Washing)
Hadith #2

عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُرَازِمٍ قَالَ رَأَيْتُ أَبَا الْحَسَنِ ( عليه السلام ) إِذَا تَوَضَّأَ قَبْلَ الطَّعَامِ لَمْ يَمَسَّ الْمِنْدِيلَ وَ إِذَا تَوَضَّأَ بَعْدَ الطَّعَامِ مَسَّ الْمِنْدِيلَ .

2. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Um ay r from Murazim who has said the following: “I saw abu al-Hassan, ‘Alayhi al-Salam, when making wudu (washing his hands) before food did not wipe his hands with a towel, but he wiped them when he (the Imam) made wudu after food.’”
