Arabic hadith text
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 ‏.‏
Translation

Malik related to me that Abd ar-Rahman ibn al-Qasim heard hisfather al-Qasim ibn Muhammad say, "I have prayed witr after dawn."

Malik said, "Only a person who oversleeps so that he does notdo the witr prays it after dawn. No one should intentionally make hiswitr after dawn."
