He Is successful who has accepted Islam, who has been provided with sufficient for his want and been made contented by Allah with what He has given him.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ قَدْ أَفْلَحَ مَنْ أَسْلَمَ وَرُزِقَ كَفَافًا وَقَنَّعَهُ اللَّهُ بِمَا آتَاهُ  

O Allah, make the provision of Muhammad's family sufficient just to sustain life.  

قَالَ رَسُولُ اللَّهِ ﷺ اللَّهُمَّ اجْعَلْ رِزْقَ آلِ مُحَمَّدٍ قُوتًا
