the Prophet said: "Precede the morning with Al-Witr."  

أَنَّ النَّبِيَّ ﷺ قَالَ بَادِرُوا الصُّبْحَ بِالْوِتْرِ  

Messenger of Allah said: "Perform Witr before the morning comes upon you."  

قَالَ رَسُولُ اللَّهِ ﷺ أَوْتِرُوا قَبْلَ أَنْ تُصْبِحُوا  

Messenger of Allah said: "When Fajr begins, then every Salat of the night and Al-Witr have gone, so perform Al-Witr before Fajr begins."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا طَلَعَ الْفَجْرُ فَقَدْ ذَهَبَ كُلُّ صَلاَةِ اللَّيْلِ وَالْوِتْرُ فَأَوْتِرُوا قَبْلَ طُلُوعِ الْفَجْرِ
