عَنِ ابْنِ عَبَّاسٍ قِيلَ لَهُ
هَلْ لَكَ فِي أَمِير الْمُؤمنِينَ مُعَاوِيَة فَإِنَّهُ مَا أَوْتَرَ إِلَّا بِوَاحِدَةٍ؟ قَالَ: أَصَابَ إِنَّهُ فَقِيهٌ وَفِي رِوَايَةٍ: قَالَ ابْنُ أَبِي مُلَيْكَةَ: أَوْتَرَ مُعَاوِيَةُ بَعْدَ الْعِشَاءِ بِرَكْعَةٍ وَعِنْدَهُ مَوْلًى لِابْنِ عَبَّاسٍ فَأَتَى ابْنَ عَبَّاسٍ فَأَخْبَرَهُ فَقَالَ: دَعْهُ فَإِنَّهُ قَدْ صَحِبَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
Ibn Abbas, on being asked whether he approved of the Commander of the Faithful, Muawiyah, using only one raka in the witr, replied, “He is right; he is versed in the law.” In a version Ibn Abu Mulaika said that Muawiyah observed a witr after the evening prayer with one raku when a client of Ibn Abbas was with him. He went to Ibn Abbas and told him, but he replied, “Leave him alone, for he was a companion of the Prophet (sallallahu alayhi wa sallam).”
