Al-Nawawi said, “It means the right of Allah is one, who has no partner or equal. It means He loves the odd and favors it in deeds and many acts of obedience. He appointed the prayer as five, ablution as three, circumambulation as seven… It is said it applies to one who worships Allah with monotheism and sincerity for Him alone.”

عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ اللهَ وِتْرٌ يُحِبُّ الْوِتْرَ
2677 صحيح مسلم كتاب الذكر والدعاء والتوبة والاستغفار باب في أسماء الله تعالى
قال النووي وَمَعْنَاهُ فِي حَقِّ اللَّهِ تَعَالَى الْوَاحِدُ الَّذِي لَا شَرِيكَ لَهُ وَلَا نَظِيرٌ وَمَعْنَى يُحِبُّ الْوِتْرَ تَفْضِيلُ الْوِتْرِ فِي الْأَعْمَالِ وَكَثِيرٍ مِنَ الطَّاعَاتِ فَجَعَلَ الصَّلَاةَ خَمْسًا وَالطَّهَارَةَ ثَلَاثًا وَالطَّوَافَ سَبْعًا … وَقِيلَ إِنَّ مَعْنَاهُ مُنْصَرِفٌ إِلَى صِفَةِ مَنْ يَعْبُدِ اللَّهَ بِالْوَحْدَانِيَّةِ وَالتَّفَرُّدِ مُخْلِصًا لَهُ
