Sahih Muslim 2538 b

This hadith has been narrated on the authority of Ibn Juraij with the same chain of transmitters, but there is no mention of the words:

" one month before his death".
حَدَّثَنِيهِ مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا مُحَمَّدُ بْنُ بَكْرٍ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ قَبْلَ مَوْتِهِ بِشَهْرٍ ‏.‏
