Mishkat al-Masabih 4 Prayer كتاب الصلاة 714

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

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.
