Abu Hurairah (RA) narrates a man said to the Prophet (S), “Oh Prophet, I heard you making this duʻā last night.” The Prophet (S) said, “Yes. Do you see how comprehensive this duʻā is? Is there anything that this duʻā leaves behind?!”
اللَّهُمَّ اغْفِرْ لِي ذَنْبِي وَوَسِّعْ لِي فِي دَارِي وَبَارِكْ لِي فِيمَا رَزَقْتَنِي
Allāhummaḡfir lī ḏambī, wa wassiʻ lī fī dārī, wa bārik lī fīmā razaqtanī
O Allah! Forgive my sins for me, expand my home for me (i.e. make me happy in my home), and bless me in the wealth and resources You have given me.
Recorded in Sunan Al-Tirmiḏi.
Al-Mubarakpuri comments on this hadith,
“Expand my home for me means make my home accommodating for me as congestion in the basic necessities of the house makes the heart congested, results in sadness and depresses the soul. It could also refer to the grave as that is the real home.
In some manuscripts, we find the wording of the hadith to be “وَوَسِّعْ لِي فِيْ رَأْيِي wa wassiʻ lī fī ra’yi Expand my opinions”, which means make me open-minded.
Bless me in wealth/resources means make my wealth and resources blessed and surrounded by goodness from all sides. It also means, “Make me content with what I have” and to not long for what others have.”
