"Whoever prays twelve rak'ahs during the night and day apart from the prescribed prayers, Allah (SWT), the Mighty and Sublime, will build for him a house in Paradise."
مَنْ صَلَّى فِي يَوْمٍ وَلَيْلَةٍ ثِنْتَىْ عَشْرَةَ رَكْعَةً سِوَى الْمَكْتُوبَةِ بَنَى اللَّهُ ﷻ لَهُ بَيْتًا فِي الْجَنَّةِ لَمْ يَرْفَعْهُ حُصَيْنٌ وَأَدْخَلَ بَيْنَ عَنْبَسَةَ وَبَيْنَ الْمُسَيَّبِ ذَكْوَانَ
