عَنْ أَبِي نَعَامَةَ أَنَّ عَبْدَ اللَّهِ بْنَ مُغَفَّلٍ رَضِيَ اللَّهُ عَنْهُ سَمِعَ ابْنًا لَهُ يَقُولُ اللَّهُمَّ إِنِّي أَسْأَلُكَ الْقَصْرَ الْأَبْيَضَ مِنَ الْجَنَّةِ إِذَا دَخَلْتُهَا وَفِي لَفْظٍ إِنِّي أَسْأَلُكَ الْفِرْدَوْسَ وَكنَا عَنْ يَمِينِي فَقَالَ أَيْ بُنَيَّ سَلِ اللَّهَ الْجَنَّةَ وَتَعَوَّذْ بِاللَّهِ مِنَ النَّارِ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ يَكُونُ فِي هَذِهِ الْأُمَّةِ قَوْمٌ يَعْتَدُونَ فِي الدُّعَاءِ وَالطُّهُورِ
It is narrated from Sayyiduna Abdullah bin Mughaffal (may Allah be pleased with him) that he heard his son supplicating in this manner: "O Allah! I ask You for a white palace in Paradise, so that when I enter it, it is on my right side." In another narration, it is: "I ask You for Paradise and such-and-such thing." So he said to his son: "O my son! Ask Allah for Paradise and seek refuge from the Fire. Indeed, I heard the Messenger of Allah (peace and blessings be upon him) say: There will be people in my Ummah who will be excessive in supplication and purification."
