[Machine] Prophet Muhammad ﷺ said that Yunus asked the Messenger of Allah ﷺ about Tayammum (dry ablution), and he replied, "Strike both hands on the ground and then wipe the face." Affan said that the Prophet ﷺ used to say regarding Tayammum, "Strike the face and the hands."  

أحمد:١٨٣١٩حَدَّثَنَا عَفَّانُ وَيُونُسُ قَالَا حَدَّثَنَا أَبَانُ حَدَّثَنَا قَتَادَةُ عَنْ عَزْرَةَ عَنْ سَعِيدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى عَنْ أَبِيهِ عَنْ عَمَّارِ بْنِ يَاسِرٍ

أَنَّ نَبِيَّ اللهِ ﷺ قَالَ يُونُسُ إِنَّهُ سَأَلَ رَسُولَ اللهِ ﷺ عَنِ التَّيَمُّمِ فَقَالَ ضَرْبَةٌ لِلْكَفَّيْنِ وَالْوَجْهِ وَقَالَ عَفَّانُ إِنَّ النَّبِيَّ ﷺ كَانَ يَقُولُ فِي التَّيَمُّمِ ضَرْبَةٌ لِلْوَجْهِ وَالْكَفَّيْنِ
