اَللّۢهُمَّ اغْفِرْلِيْ ذَنْۘبِيْ، وَ وَسِّعْ لِيْ فِيْ دَارِيْ، وَبَارِكْ لِيْ فِيْ رِزْقِيْ ـ

Allaahummagh-fir lii dhambii, wa wassi’ lii fii daarii, wa baarik lii fii rizqii. (Abu Hurayrah. Kanz al-‘Ummal #3633)

O Allah, forgive my sin, make my home ample for me, and bless me in my sustenance.

This du’aa should also be recited when making wudu.
