البيهقي:٤٥٣٢ – وَبِإِسْنَادِهِ قَالَ ثنا مَالِكٌ عَنْ يَحْيَى بْنِ سَعِيدٍ أَنَّهُ قَالَ كَانَ عُبَادَةُ بْنُ الصَّامِتِ يَؤُمُّ قَوْمَنَا فَخَرَجَ يَوْمًا إِلَى الصُّبْحِ فَأَقَامَ الْمُؤَذِّنُ الصَّلَاةَ فَأَسْكَتَهُ عُبَادَةُ حَتَّى أَوْتَرَ ثُمَّ صَلَّى لَهُمُ الصُّبْحَ قَالَ مَالِكٌ وَإِنَّمَا يُوتِرُ بَعْدَ الْفَجْرِ مَنْ نَامَ عَنِ الْوِتْرِ وَلَا يَنْبَغِي لِأَحَدٍ

أَنْ يَتَعَمَّدَ ذَلِكَ حَتَّى يَضَعَ وِتْرَهُ بَعْدَ الْفَجْرِ

Malik related to me that Abd ar-Rahman ibn al-Qasim heard his father al-Qasim ibn Muhammad say, "I have prayed witr after dawn." Malik said, "Only a person who oversleeps so that he does not do the witr prays it after dawn. No one should intentionally make his witr after dawn."  

مالك:٧-٢٨ – وَحَدَّثَنِي مَالِكٌ عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ أَنَّهُ سَمِعَ أَبَاهُ الْقَاسِمَ بْنَ مُحَمَّدٍ يَقُولُ

إِنِّي لأُوتِرُ بَعْدَ الْفَجْرِ قَالَ مَالِكٌ وَإِنَّمَا يُوتِرُ بَعْدَ الْفَجْرِ مَنْ نَامَ عَنِ الْوِتْرِ وَلاَ يَنْبَغِي لأَحَدٍ أَنْ يَتَعَمَّدَ ذَلِكَ حَتَّى يَضَعَ وِتْرَهُ بَعْدَ الْفَجْرِ
