Musnad Ahmad #884
Musnad 'Ali Ibn Abi Talib
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَنْبَأَنَا إِسْرَائِيلُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْحَارِثِ، عَنْ عَلِيٍّ، أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يُوتِرُ عِنْدَ الْأَذَانِ.
It was narrated from ‘Ali (رضي الله عنه) that The Prophet (ﷺ) used to pray Witr at the time of the adhan.
