Muwatta Malik, Book 6, Hadith 252 (In-Book)

Yahya related to me from Malik from Da'ud ibn al-Husayn that he heard al-Araj say, "I never saw the people in Ramadan, but that they were cursing the disbelievers." He added, "The reciter of Qur'an used to recite surat al-Baqara in eight rakas and if he did it in twelve rakas the people would think that he had made it easy."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ دَاوُدَ بْنِ الْحُصَيْنِ، أَنَّهُ سَمِعَ الأَعْرَجَ، يَقُولُ مَا أَدْرَكْتُ النَّاسَ إِلاَّ وَهُمْ يَلْعَنُونَ الْكَفَرَةَ فِي رَمَضَانَ ‏.‏ قَالَ وَكَانَ الْقَارِئُ يَقْرَأُ سُورَةَ الْبَقَرَةِ فِي ثَمَانِ رَكَعَاتٍ فَإِذَا قَامَ بِهَا فِي اثْنَتَىْ عَشْرَةَ رَكْعَةً رَأَى النَّاسُ أَنَّهُ قَدْ خَفَّفَ ‏.‏
