[Machine] If a person avoids washing during travel and the time for prayer arrives, then if they cannot find water, they should perform dry ablution (tayammum). The prayer of Al-Harith Al-A'war is not used as evidence.
إِذَا أَجْنَبَ الرَّجُلُ فِي السَّفَرِ تَلَوَّمَ مَا بَيْنَهُ وَبَيْنَ آخِرِ الْوَقْتِ فَإِنْ لَمْ يَجِدِ الْمَاءَ تَيَمَّمَ وَصَلَّى الْحَارِثُ الْأَعْوَرُ لَا يُحْتَجُّ بِهِ
