[Machine] The Messenger of Allah ﷺ used to perform ablution (wudu') while wearing a Qatari turban (imamah), then he would put his hand under the turban and wipe the front part of his head without uncovering the turban. Although this hadith may not meet the criteria set by scholars, it contains an unusual phrase stating that he wiped a part of his head without wiping his turban. If this is correct, it indicates that he wiped a part of his head.  

كَانَ رَسُولُ اللَّهِ ﷺ «يَتَوَضَّأُ وَعَلَيْهِ عِمَامَةٌ قِطْرِيَّةٌ فَأَدْخَلَ يَدَهُ مِنْ تَحْتِ الْعِمَامَةِ فَمَسَحَ مُقَدَّمَ رَأْسِهِ وَلَمْ يَنْقُضِ الْعِمَامَةَ» «هَذَا الْحَدِيثُ وَإِنْ لَمْ يَكُنْ إِسْنَادُهُ مِنْ شَرْطِ الْكِتَابِ فَإِنَّ فِيهِ لَفْظَةً غَرِيبَةً وَهِيَ أَنَّهُ مَسَحَ عَلَى بَعْضِ الرَّأْسِ وَلَمْ يَمْسَحْ عَلَى عِمَامَتِهِ» لو صح لدل على مسح بعض الرأس
