On Judgement Day, superiority will be granted to the one who suppresses his anger

The Messenger of Allah ﷺ said: If anyone suppresses anger when he is in a position to give vent to it, Allah, the Exalted, will call him on the Day of Resurrection over the heads of all creatures, and ask him to choose any of the bright and large-eyed maidens he wishes.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ: «مَنْ كَظَمَ غَيْظًا وَهُوَ قَادِرٌ عَلَى أَنْ يُنْفِذَهُ، دَعَاهُ اللَّهُ ﷻ عَلَى رُءُوسِ الْخَلاَئِقِ يَوْمَ الْقِيَامَةِ حَتَّى يُخَيِّرَهُ اللَّهُ مِنَ الْحُورِ مَا شَاءَ۔»  

He then mentioned a similar tradition described above. This version has: Allah will fill his heart with security and faith. He did not mention the words "Allah will call him". This version further adds: He who gives up wearing beautiful garments when he is able to do so (out of humility, as Bishr's version has) will be clothed by Allah with the robe of honour, and he who marries for Allah's sake will be crowned by Allah with the crown of Kingdom.  

عَنْ رَجُلٍ مِنْ أَبْنَاءِ أَصْحَابِ النَّبِيِّ ﷺ عَنْ أَبِيهِ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ نَحْوَهُ قَالَ مَلأَهُ اللَّهُ أَمْنًا وَإِيمَانًا لَمْ يَذْكُرْ قِصَّةَ دَعَاهُ اللَّهُ زَادَ وَمَنْ تَرَكَ لُبْسَ ثَوْبِ جَمَالٍ وَهُوَ يَقْدِرُ عَلَيْهِ قَالَ بِشْرٌ أَحْسِبُهُ قَالَ تَوَاضُعًا كَسَاهُ اللَّهُ حُلَّةَ الْكَرَامَةِ وَمَنْ زَوَّجَ لِلَّهِ تَعَالَى تَوَّجَهُ اللَّهُ تَاجَ الْمُلْكِ  

Whom do you consider a wrestler among you? The people replied: (the man) whom the men cannot defeat in wrestling. He said: No, it is he who controls himself when he is angry.  

قَالَ رَسُولُ اللَّهِ ﷺ مَا تَعُدُّونَ الصُّرَعَةَ فِيكُمْ قَالُوا الَّذِي لاَ يَصْرَعُهُ الرِّجَالُ قَالَ لاَ وَلَكِنَّهُ الَّذِي يَمْلِكُ نَفْسَهُ عِنْدَ الْغَضَبِ
