Abu Huraira reported that Messenger of Allah ﷺ was travelling along the path leading to Mecca that he happened to pass by a mountain called Jumdan. He said: Proceed on, it is Jumdan, Mufarradun have gone ahead. They (the Companions of the Holy Prophet) said: Allah's Messenger, who are Mufarradun? 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 ﷺ
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 " .
