Apabila khawatir masuk waktu subuh, maka shalatlah witir satu rakat
Imam Bukhari : 1069حَدَّثَنَا أَبُو الْيَمَانِ قَالَ أَخْبَرَنَا شُعَيْبٌ عَنْ الزُّهْرِيِّ قَالَ أَخْبَرَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَإِنَّ رَجُلًا قَالَ يَا رَسُولَ اللَّهِ كَيْفَ صَلَاةُ اللَّيْلِ قَالَ مَثْنَى مَثْنَى فَإِذَا خِفْتَ الصُّبْحَ فَأَوْتِرْ بِوَاحِدَةٍ
Abu Al-Yaman narrated to us, Shu'aib informed us, from Az-Zuhri, who Sa'd Salim bin Abdullah informed me that Abdullah bin 'Umar (may Allah be pleased with them) said: A man asked, 'O Messenger of Allah, how is the night prayer performed?' He Sa'd 'Two by two, and if you fear the dawn, perform Witr with one rak'ah.'
