وَعَن عبد الله بن الْمُغَفَّل أَنه سمع ابْنه يَقُول: الله إِنِّي أَسْأَلُكَ الْقَصْرَ الْأَبْيَضَ عَنْ يَمِينِ الْجَنَّةِ قَالَ: أَيْ بُنَيَّ سَلِ اللَّهَ الْجَنَّةَ وَتَعَوَّذْ بِهِ مِنَ النَّارِ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُول: «إِنَّه سَيكون فِي هَذِهِ الْأُمَّةِ قَوْمٌ يَعْتَدُونَ فِي الطَّهُورِ وَالدُّعَاءِ» . رَوَاهُ أَحْمَدُ وَأَبُو دَاوُدَ وَابْنُ مَاجَهْ
English Translation
‘Abdallah b. al-Mughaffal on hearing his son say, “O God, I ask Thee for the white palace on the right of paradise,” said, “Sonny, ask God for paradise and seek refuge in Him from hell, for I heard God’s Messenger say, ‘There will be some among this people who will go over the score in ablution and supplication.” Ahmad, Abu Dawud and Ibn Majah transmitted it.
