باب فَضْلِ الذِّكْرِ وَالدُّعَاءِ وَالتَّقَرُّبِ إِلَى اللَّهِ تَعَالَى
Sahih Muslim 2675 f

This hadith has been narrated on the authority of Mu'tamar from his father with the same chain of transmitters, with a slight variation of wording.

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى الْقَيْسِيُّ، حَدَّثَنَا مُعْتَمِرٌ، عَنْ أَبِيهِ، بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ ‏ "‏ إِذَا أَتَانِي يَمْشِي أَتَيْتُهُ هَرْوَلَةً ‏"‏ ‏.‏
