Narrated Sa'd ibn AbuWaqqas:

Ibn Sa'd said: My father (Sa'd ibn AbuWaqqas) heard me say: O Allah, I ask You for Paradise, its blessings, its pleasure and such-and-such, and such-and-such; I seek refuge in You from Hell, from its chains, from its collars, and from such-and-such, and from such-and-such. He said: I heard the Messenger of Allah (ﷺ) say: There will be people who will exaggerate in supplication. You should not be one of them. If you are granted Paradise, you will be granted all what is good therein; if you are protected from Hell, you will be protected from what is evil therein.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، عَنْ زِيَادِ بْنِ مِخْرَاقٍ، عَنْ أَبِي نُعَامَةَ، عَنِ ابْنٍ لِسَعْدٍ، أَنَّهُ قَالَ سَمِعَنِي أَبِي، وَأَنَا أَقُولُ اللَّهُمَّ، إِنِّي أَسْأَلُكَ الْجَنَّةَ وَنَعِيمَهَا وَبَهْجَتَهَا وَكَذَا وَكَذَا وَأَعُوذُ بِكَ مِنَ النَّارِ وَسَلاَسِلِهَا وَأَغْلاَلِهَا وَكَذَا وَكَذَا فَقَالَ يَا بُنَىَّ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏

‏ سَيَكُونُ قَوْمٌ يَعْتَدُونَ فِي الدُّعَاءِ ‏

‏ ‏.‏ فَإِيَّاكَ أَنْ تَكُونَ مِنْهُمْ إِنْ أُعْطِيتَ الْجَنَّةَ أُعْطِيتَهَا وَمَا فِيهَا مِنَ الْخَيْرِ وَإِنْ أُعِذْتَ مِنَ النَّارِ أُعِذْتَ مِنْهَا وَمَا فِيهَا مِنَ الشَّرِّ ‏.‏
