وَيُكْرَهُ لِلْمُتَوَضِّئِ سِتَّةُ أَشْيَاءَ: الْإِسْرَافُ فِي الْمَاءِ، وَالتَّقْتِيرُ فِيهِ، وَضَرْبُ الْوَجْهِ بِهِ، وَالتَّكَلُّمُ بِكَلَامِ النَّاسِ، وَالِاسْتِعَانَةُ بِغَيْرِهِ مِنْ غَيْرِ عُذْرٍ، وَتَثْلِيثُ الْمَسْحِ بِمَاءٍ جَدِيدٍ
1. Excessive water use.
2. Using water so sparingly that proper washing resembles mere wiping.
3. Striking/splashing water harshly onto the face.
4. Worldly conversation.
5. Seeking another's help without excuse.
6. Wiping the head three times with fresh water.
If so little water is used that an obligatory area is not actually washed, the issue becomes invalid washing, not merely dislike.
