Muwatta Malik, Book 6, Hadith 253 (In-Book)

Yahya related to me from Malik that Abdullah ibn Abi Bakr said, "I heard my father say, 'We finished praying in Ramadan and the servants hurried with the food, fearing the approach of dawn.' "

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، قَالَ سَمِعْتُ أَبِي يَقُولُ، كُنَّا نَنْصَرِفُ فِي رَمَضَانَ فَنَسْتَعْجِلُ الْخَدَمَ بِالطَّعَامِ مَخَافَةَ الْفَجْرِ ‏.‏
