حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، حَدَّثَنَا سَعِيدٌ الْجُرَيْرِيُّ، عَنْ أَبِي نَعَامَةَ، أَنَّ عَبْدَ اللَّهِ بْنَ مُغَفَّلٍ، سَمِعَ ابْنَهُ، يَقُولُ اللَّهُمَّ إِنِّي أَسْأَلُكَ الْقَصْرَ الأَبْيَضَ عَنْ يَمِينِ الْجَنَّةِ، إِذَا دَخَلْتُهَا ‏.‏ فَقَالَ أَىْ بُنَىَّ سَلِ اللَّهَ الْجَنَّةَ وَتَعَوَّذْ بِهِ مِنَ النَّارِ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏ إِنَّهُ سَيَكُونُ فِي هَذِهِ الأُمَّةِ قَوْمٌ يَعْتَدُونَ فِي الطُّهُورِ وَالدُّعَاءِ ‏"‏ ‏.‏

Narrated Abdullah ibn Mughaffal: Abdullah heard his son praying to Allah: O Allah, I ask Thee a white palace on the right of Paradise when I enter it. He said: O my son, ask Allah for Paradise and seek refuge in Him from Hell-Fire, for I heard the Messenger of Allah (PBUH) say: In this community there will be some people who will exceed the limits in purification as well as in supplication.
