صَحِيحُ الْبُخَارِيِّ
Sahih al-Bukhari 340
Rubbing hands and feet with dust (Tayammum)
Tayammum is for the hands and the face
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ ذَرٍّ، عَنِ ابْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى، عَنْ أَبِيهِ، أَنَّهُ شَهِدَ عُمَرَ وَقَالَ لَهُ عَمَّارٌ كُنَّا فِي سَرِيَّةٍ فَأَجْنَبْنَا، وَقَالَ تَفَلَ فِيهِمَا.
Narrated `Abdur Rahman bin Abza: that while he was in the company of `Umar, `Ammar said to `Umar, "We were in a detachment and became Junub and I blew the dust off my hands (performed the rolling over the earth and prayed.)"
