Sahih (Sahih Muslim)
وَحَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ الدَّارِمِيُّ، أَخْبَرَنَا يَحْيَى بْنُ حَسَّانَ، حَدَّثَنِي مُعَاوِيَةُ، أَخْبَرَنِي أَخِي، زَيْدٌ بِهَذَا الإِسْنَادِ . مِثْلَهُ غَيْرَ أَنَّهُ قَالَ " أَوْ أَمَرَ بِمَعْرُوفٍ " . وَقَالَ " فَإِنَّهُ يُمْسِي يَوْمَئِذٍ " .
This hadith has been narrated on the authority of Zaid with the same chain of transmitters except with (a slight) change of words (i.e. he [the Holy Prophet]) said:Or he enjoined what is good, ... and said: He enters the evening [i.e. he walks till evening]
