Hadith 2:284
Narrated Talq bin 'Ali (RA):
I heard Allah's Messenger (ﷺ) saying, "There are no two Witr (prayers) during one night." [Reported by Ahmad and ath-Thalathah and Ibn Hibban graded it Sahih (authentic)].
وَعَنْ طَلْقٍ بْنِ عَلِيٍّ - رضى الله عنه - قَالَ: سَمِعْتَ رَسُولَ اَللَّهِ - صلى الله عليه وسلم -يَقُولُ: { لَا وِتْرَانِ فِي لَيْلَةٍ } رَوَاهُ أَحْمَدُ, وَالثَّلَاثَةُ, وَصَحَّحَهُ اِبْنُ حِبَّانَ
