Sahih al-Bukhari
Rubbing hands and feet with dust (Tayammum)
Chapter
Narrated Jabir bin `Abdullah:
The Prophet (ﷺ) said, "I have been given five things which were not given to any one else before me. -1. Allah made me victorious by awe, (by His frightening my enemies) for a distance of one month's journey. -2. The earth has been made for me (and for my followers) a place for praying and a thing to perform Tayammum, therefore anyone of my followers can pray wherever the time of a prayer is due. -3. The booty has been made Halal (lawful) for me yet it was not lawful for anyone else before me. -4. I have been given the right of intercession (on the Day of Resurrection). -5. Every Prophet used to be sent to his nation only but I have been sent to all mankind.
