Bulugh al-Maram 129
In a version by Al-Bukhari, `Ammar said:
'He (ﷺ) struck the earth with the palms of his hands, blew in them and wiped his face and hands with them.
وَفِي رِوَايَةٍ لِلْبُخَارِيِّ: وَضَرَبَ بِكَفَّيْهِ اَلْأَرْضَ, وَنَفَخَ فِيهِمَا, ثُمَّ مَسَحَ بِهِمَا وَجْهَهُ وَكَفَّيْه ِ  1‏ .‏‏1 ‏- البخاري رقم (338)‏.‏
