'Abdullah bin Mughaffal heard his son say: "O Allah, I ask You for the white palace on the right-hand side of Paradise, when I enter it." He said: "O my son, ask Allah for Paradise and seek refuge with Him from Hell, for I heard the Messenger of Allah (saas) say: 'There will be people who will transgress in supplication.'" (Using translation from Ibn Mājah 3864)
سَمِعَ ابْنَهُ يَقُولُ اللهُمَّ إِنِّي أَسْأَلُكَ الْقَصْرَ الْأَبْيَضَ عَنْ يَمِينِ الْجَنَّةِ إِذَا دَخَلْتُهَا فَقَالَ يَا بُنَيَّ سَلِ اللهَ الْجَنَّةَ وَعُذْ بِهِ مِنَ النَّارِ فَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ يَكُونُ قَوْمٌ يَعْتَدُونَ فِي الدُّعَاءِ وَالطَّهُورِ
