Muwatta Malik 676

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ، وَأَبَا، هُرَيْرَةَ اخْتَلَفَا فِي قَضَاءِ رَمَضَانَ فَقَالَ أَحَدُهُمَا يُفَرِّقُ بَيْنَهُ ‏.‏ وَقَالَ الآخَرُ لاَ يُفَرِّقُ بَيْنَهُ ‏.‏ لاَ أَدْرِي أَيَّهُمَا قَالَ يُفَرِّقُ بَيْنَهُ ‏.‏

Yahya related to me from Malik from Ibr Shihab that Abdullah ibn Abbas and Abu Hurayra differed about making up days missed in Ramadan. One of them said that they were done separately and the other said that they were done consecutively. He did not know which one of them it was who said that they were done separately
