The Prophet ﷺ said, "One of the sayings of the prophets which the people have got is, 'If you do not feel ashamed, then do whatever you like."  

قَالَ النَّبِيُّ ﷺ إِنَّ مِمَّا أَدْرَكَ النَّاسُ مِنْ كَلاَمِ النُّبُوَّةِ إِذَا لَمْ تَسْتَحِي فَاصْنَعْ مَا شِئْتَ  

The Prophet ﷺ said, "While a man was walking, dragging his dress with pride, he was caused to be swallowed by the earth and will go on sinking in it till the Day of Resurrection."  

أَنَّ النَّبِيَّ ﷺ قَالَ بَيْنَمَا رَجُلٌ يَجُرُّ إِزَارَهُ مِنَ الْخُيَلاَءِ خُسِفَ بِهِ فَهْوَ يَتَجَلْجَلُ فِي الأَرْضِ إِلَى يَوْمِ الْقِيَامَةِ  

The Prophet ﷺ said, "We are the last (to come) but we will be the foremost on the Day of Resurrection, nations were given the Book (i.e. Scripture) before us, and we were given the Holy Book after them. This (i.e. Friday) is the day about which they differed. So the next day (i.e. Saturday) was prescribed for the Jews and the day after it (i.e. Sunday) for the Christians. It is incumbent on every Muslim to wash his head and body on a Day (i.e. Friday) (at least) in every seven days."  

عَنِ النَّبِيِّ ﷺ قَالَ نَحْنُ الآخِرُونَ السَّابِقُونَ يَوْمَ الْقِيَامَةِ بَيْدَ كُلُّ أُمَّةٍ أُوتُوا الْكِتَابَ مِنْ قَبْلِنَا وَأُوتِينَا مِنْ بَعْدِهِمْ فَهَذَا الْيَوْمُ الَّذِي اخْتَلَفُوا فَغَدًا لِلْيَهُودِ وَبَعْدَ غَدٍ لِلنَّصَارَى عَلَى كُلِّ مُسْلِمٍ فِى كُلِّ سَبْعَةِ أَيَّامٍ يَوْمٌ يَغْسِلُ رَأْسَهُ وَجَسَدَهُ  

When Muawiya bin Abu Sufyan came to Medina for the last time, he delivered a sermon before us. He took out a tuft of hair and said, "I never thought that someone other than the Jews would do such a thing (i.e. use false hair). The Prophet ﷺ named such a practice, 'Az-Zur' (i.e. falsehood)," meaning the use of false hair.  

أَنَّ أَحَدًا يَفْعَلُ هَذَا غَيْرَ الْيَهُودِ وَإِنَّ النَّبِيَّ ﷺ سَمَّاهُ الزُّورَ يَعْنِي الْوِصَالَ فِي الشَّعَرِ
