The Messenger of Allah ﷺ said, "Do not perform Witr (the odd numbered nightly prayer) to three rakahs making is seem like the Maghrib prayer. Rather extend it to five, or seven."  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ «لَا تُوتِرُوا بِثَلَاثٍ وَلَا تَشَبَّهُوا بِصَلَاةِ الْمَغْرِبِ أَوْتِرُوا بِخَمْسٍ أَوْ بِسَبْعٍ»  

[Machine] From the Messenger of Allah ﷺ that he said, "Do not perform Witr (an odd number of units of prayer) with three (units of prayer), rather perform it with five or seven. And do not resemble the Maghrib prayer."  

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ «لَا تُوتِرُوا بِثَلَاثٍ أَوْتِرُوا بِخَمْسٍ أَوْ بِسَبْعٍ وَلَا تَشَبَّهُوا بِصَلَاةِ الْمَغْرِبِ»  

[Machine] The Messenger of Allah ﷺ said, "Do not make it difficult for yourselves with three things: resembling the Maghrib prayer, performing the Witr prayer with seven units, or performing it with five units."  

قَالَ رَسُولُ اللهِ ﷺ لَا تُوتِرُوا بِثَلَاثٍ تُشَبِّهُوا بِصَلَاةِ الْمَغْرِبِ أَوْتِرُوا بِسَبْعٍ أَوْ بِخَمْسٍ  

[Machine] The Messenger of Allah ﷺ said, "Do not be steadfast in praying three rak'ahs that resemble the Maghrib (sunset) prayer, but rather be steadfast in praying five rak'ahs or seven rak'ahs or nine rak'ahs or eleven rak'ahs or more than that." Ibn Bukair narrated this from Al-Layth.  

قَالَ رَسُولُ اللهِ ﷺ لَا تُوتِرُوا بِثَلَاثٍ تُشَبِّهُوا بِالْمَغْرِبِ وَلَكِنْ أَوْتِرُوا بِخَمْسٍ أَوْ بِسَبْعٍ أَوْ بِتِسْعٍ أَوْ بِإِحْدَى عَشْرَةَ رَكْعَةً أَوْ أَكْثَرَ مِنْ ذَلِكَ وَرَوَاهُ ابْنُ بُكَيْرٍ عَنِ اللَّيْثِ كَمَا  

"لَا تُوتِرُوا بثَلَاث تَشَبَّهُوا بِالْمَغرِبِ، وَلَكِنْ أَوْتِرُوا بِخَمْسٍ أَوْ بِسَبْعٍ، أوْ بِتِسْعٍ، أَوْ بِإِحْدَى عَشْرَةَ أَوْ أَكْثَرَ مِنْ ذَلِكَ".
