Abu Huraira reported that Allah's Messenger was travelling along the path leading to Mecca that he happened to pass by a mountain called Jumdan.

He said: They are those males and females who remember Allah much.
حَدَّثَنَا أُمَيَّةُ بْنُ بِسْطَامَ الْعَيْشِيُّ، حَدَّثَنَا يَزِيدُ، - يَعْنِي ابْنَ زُرَيْعٍ - حَدَّثَنَا رَوْحُ، بْنُ الْقَاسِمِ عَنِ الْعَلاَءِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَسِيرُ فِي طَرِيقِ مَكَّةَ فَمَرَّ عَلَى جَبَلٍ يُقَالُ لَهُ جُمْدَانُ فَقَالَ " سِيرُوا هَذَا جُمْدَانُ سَبَقَ الْمُفَرِّدُونَ " . قَالُوا وَمَا الْمُفَرِّدُونَ يَا رَسُولَ اللَّهِ قَالَ " الذَّاكِرُونَ اللَّهَ كَثِيرًا وَالذَّاكِرَاتُ " .
