The Messenger of Allah ﷺ sent out an expedition. They were affected by cold. When they returned to the Messenger of Allah ﷺ, he commanded them to wipe over turbans and stockings.  

بَعَثَ رَسُولُ اللَّهِ ﷺ سَرِيَّةً فَأَصَابَهُمُ الْبَرْدُ فَلَمَّا قَدِمُوا عَلَى رَسُولِ اللَّهِ ﷺ أَمَرَهُمْ أَنْ يَمْسَحُوا عَلَى الْعَصَائِبِ وَالتَّسَاخِينِ  

I saw the Messenger ﷺ perform ablution. He had a Qutri turban. He inserted his hand beneath the turban and wiped over the forelock, and did not untie the turban.  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَتَوَضَّأُ وَعَلَيْهِ عِمَامَةٌ قِطْرِيَّةٌ فَأَدْخَلَ يَدَهُ مِنْ تَحْتِ الْعِمَامَةِ فَمَسَحَ مُقَدَّمَ رَأْسِهِ وَلَمْ يَنْقُضِ الْعِمَامَةَ
