Sahih Muslim, Hadith 1149d

باب قَضَاءِ الصِّيَامِ عَنِ الْمَيِّتِ

وَحَدَّثَنِيهِ إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، عَنْ سُفْيَانَ، بِهَذَا الإِسْنَادِ وَقَالَ صَوْمُ شَهْرَيْنِ ‏.‏

This hadith has been narrated on the authority of Sufyan with the same chain of transmitters in which it is said:

" Fasting of two months."
