Mishkat al-Masabih 1303
Al-A‘raj said:
I never came upon the people without hearing them cursing the infidels during Ramadan. The reader recited sura al-Baqara (Al-Qur’an; 2) in the course of eight rak'as , and when he made it serve for twelve rak'as the people thought he had shortened the prayer. 

Malik transmitted it.
وَعَن الْأَعْرَج قَالَ: مَا أَدْرَكْنَا النَّاسَ إِلَّا وَهُمْ يَلْعَنُونَ الْكَفَرَةَ فِي رَمَضَانَ قَالَ: وَكَانَ الْقَارِئُ يَقْرَأُ سُورَةَ الْبَقَرَةِ فِي ثَمَانِ رَكَعَاتٍ وَإِذَا قَامَ بِهَا فِي ثِنْتَيْ عَشْرَةَ رَكْعَةً رَأَى النَّاسُ أَنه قد خفف. رَوَاهُ مَالك
