Hadith 4644
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا ابْنُ إِدْرِيسَ، عَنِ الأَعْمَشِ، قَالَ سَمِعْتُ الْحَجَّاجَ، يَقُولُ عَلَى الْمِنْبَرِ هَذِهِ الْحَمْرَاءُ هَبْرٌ هَبْرٌ أَمَا وَاللَّهِ لَقَدْ قَرَعْتُ عَصًا بِعَصًا لأَذَرَنَّهُمْ كَالأَمْسِ الذَّاهِبِ يَعْنِي الْمَوَالِي .
Al-A’mash said:These clients (i.e., non-Arabs) are to be struck and cut off. I swear by Allah, if I strike a stick with a stick, I would annihilate them like the day that passed away. Al-hamra means clients or non-Arabs
