[Machine] The Messenger of Allah ﷺ said that whoever leaves even a hair's breadth of his body unwashed from ritual impurity, it will be punished with the fire. Ali said, "Therefore, I have become an enemy of my hair." This hadith and its meaning necessitate the proper washing of it. The book also necessitates the use of tayammum for what cannot be washed. By Allah's guidance, the apparent meaning of the book indicates the use of whatever water one finds, and then resorting to tayammum if one cannot find water. It has been narrated from Ishaq from Isa bin Yunus from Abdah bin Abi Lubabah, and it is mentioned about Abdah bin Abi Lubabah that he said that he would perform wudu and tayammum in a state of major impurity if he could not find water except what is required for wudu. Similarly, Ma'mar bin Rashid said the same, and Hasan and Zuhri would say the same.  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ تَرَكَ مَوْضِعَ شَعْرَةٍ مِنْ جَسَدِهِ مِنْ جَنَابَةٍ لَمْ يَغْسِلْهَا فُعِلَ بِهَا مَنِ النَّارِ كَذَا وَكَذَا قَالَ عَلِيٌّ فَمِنْ ثَمَّ عَادَيْتُ شَعْرِي فَهَذَا الْحَدِيثُ وَمَا وَرَدَ فِي مَعْنَاهُ يُوجِبُ غُسْلَ الصَّحِيحِ مَنْهُ وَالْكِتَابُ يُوجِبُ التَّيَمُّمَ لِمَا لَا يُقْدَرُ عَلَى غَسْلِهِ وَبِاللهِ التَّوْفِيقُ وَظَاهِرُ الْكِتَابِ يَدُلُّ عَلَى اسْتِعْمَالِ مَا يَجِدُ مِنَ الْمَاءِ ثُمَّ الرُّجُوعُ إِلَى التَّيَمُّمِ إِذَا لَمْ يَجِدْهُ وَقَدْ رُوِيَ عَنْ إِسْحَاقَ عَنْ عِيسَى بْنِ يُونُسَ عَنْ عَبْدَةَ بْنِ أَبِي لُبَابَةَ وَيُذْكَرُ عَنْ عَبْدَةَ بْنِ أَبِي لُبَابَةَ أَنَّهُ قَالَ يَتَوَضَّأُ وَيَتَيَمَّمُ فِي الْجُنُبِ لَا يَجِدُ مِنَ الْمَاءِ إِلَّا قَدْرَ مَا يَتَوَضَّأُ وَكَذَا قَالَ مَعْمَرُ بْنُ رَاشِدٍ وَكَانَ الْحَسَنُ وَالزُّهْرِيُّ يَقُولَانِ يَتَيَمَّمُ
