Full Sharh — Sahih Muslim 2606
حَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، بِهَذَا الإِسْنَادِ قَالَ الزُّهْرِيُّ وَكَانَ الْفِطْرُ آخِرَ الأَمْرَيْنِ وَإِنَّمَا يُؤْخَذُ مِنْ أَمْرِ رَسُولِ اللَّهِ صلى الله عليه وسلم بِالآخِرِ فَالآخِرِ . قَالَ الزُّهْرِيُّ فَصَبَّحَ رَسُولُ اللَّهِ صلى الله عليه وسلم مَكَّةَ لِثَلاَثَ عَشْرَةَ لَيْلَةً خَلَتْ مِنْ رَمَضَانَ .
English Translation
It has been narrated on the authority of Zuhri with the same chain of transmitters that breaking of fast (in a journey) is the final of the two commands (whether one may fast or one may break it), and it is the last command of the Messenger of Allah (ﷺ) which is to be accepted as final. Zuhri said:The Messenger of Allah (ﷺ) marched on Mecca on the morning of 14th of Ramadan (lit. when thirteen nights had passed)
