Arabic (Original)
وحَدَّثناه محمد حَدَّثنا عَبْدُ الرَّحمَن عَن هِشَامٍ عَن قَتادة عَن أَنَس أَن النَّبِيّ صَلَّى اللَّهُ عَلَيه وَسَلَّم قَنَتَ شَهْرًا يَدْعُو عَلَى حَيٍّ مِنْ أَحْيَاءِ الْعَرَبِ ثُمَّ تَرَكَهُ عَلَيه وَسَلَّم قَنَتَ شَهْرًا يَدْعُو عَلَى حَيٍّ مِنْ أَحْيَاءِ الْعَرَبِ ثُمَّ تَرَكَهُ
English Translation
And Muhammad narrated to us: Abdur-Rahman narrated to us from Hisham from Qatadah from Anas that the Noble Prophet (blessings and peace of Allah be upon him) made the supplication of Qunut for a month, invoking against a tribe from the Arab tribes, then he ceased doing so.
