The Messenger of Allah ﷺ said: "Prayer at night is two by two, then when you want to finish, pray one rak'h which will make the total number that you prayed odd."
عَنْ رَسُولِ اللَّهِ ﷺ قَالَ صَلاَةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا أَرَدْتَ أَنْ تَنْصَرِفَ فَارْكَعْ بِوَاحِدَةٍ تُوتِرُ لَكَ مَا قَدْ صَلَّيْتَ
Once a person asked Messenger of Allah ﷺ ﷺ about the night prayer. Allah's Apostle ﷺ replied, "The night prayer is offered as two Rakʿat followed by two Rakʿat and so on and if anyone is afraid of the approaching dawn (Fajr prayer) he should pray one Rakʿah and this will be a Witr for all the Rakʿat which he has prayed before."
أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ عَنْ صَلاَةِ اللَّيْلِ فَقَالَ رَسُولُ اللَّهِ ﷺ صَلاَةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَحَدُكُمُ الصُّبْحَ صَلَّى رَكْعَةً وَاحِدَةً تُوتِرُ لَهُ مَا قَدْ صَلَّى
Prayer during the night should consist of pairs of rak'ahs, but if one of you fears morning is near, he should pray one rak'ah which will make his prayer an odd number for him.
أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ عَنْ صَلاَةِ اللَّيْلِ فَقَالَ رَسُولُ اللَّهِ ﷺ صَلاَةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَحَدُكُمُ الصُّبْحَ صَلَّى رَكْعَةً وَاحِدَةً تُوتِرُ لَهُ مَا قَدْ صَلَّى

Yahya related to me from Malik from Nafi and Abdullah ibn Umar that a man asked the Messenger of Allah ﷺ about night prayers. The Messenger of Allah ﷺ said, "Night prayers are two by two, and when you are afraid that dawn is approaching, pray one raka to make what you have prayed odd."
أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ عَنْ صَلاَةِ اللَّيْلِ فَقَالَ رَسُولُ اللَّهِ ﷺ صَلاَةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَحَدُكُمُ الصُّبْحَ صَلَّى رَكْعَةً وَاحِدَةً تُوتِرُ لَهُ مَا قَدْ صَلَّى

"صَلاةُ اللَّيل مَثْنَى مَثْنَى، فَإِذَا خَشِى أَحَدُكُمُ الصُّبْحَ صَلَّى رَكْعَةً وَاحِدَةً تُوتِرُ لهُ مَا قَدْ صلَّى".
