حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا أَبُو يَحْيَى الْقَتَّاتُ، عَنْ مُجَاهِدٍ، قَالَ كُنْتُ مَعَ ابْنِ عُمَرَ فَثَوَّبَ رَجُلٌ فِي الظُّهْرِ أَوِ الْعَصْرِ قَالَاخْرُجْ بِنَا فَإِنَّ هَذِهِ بِدْعَةٌ ‏.‏
Translation
Narrated Abdullah ibn Umar

Mujahid reported: I was with Ibn Umar when a man made the call for the noon or the afternoon prayer. He said: Go out with us, for this is an innovation.
