'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.'"  

سَمِعَ ابْنَهُ يَقُولُ اللَّهُمَّ إِنِّي أَسْأَلُكَ الْقَصْرَ الأَبْيَضَ عَنْ يَمِينِ الْجَنَّةِ إِذَا دَخَلْتُهَا فَقَالَ أَىْ بُنَىَّ سَلِ اللَّهَ الْجَنَّةَ وَعُذْ بِهِ مِنَ النَّارِ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ سَيَكُونُ قَوْمٌ يَعْتَدُونَ فِي الدُّعَاءِ
