Blessing in what your household measures out
The Prophet ﷺ asked for blessing in the very units they weighed food with.
اللَّهُمَّ بَارِكْ لَنَا فِي صَاعِنَا وَمُدِّنَا
Allāhumma bārik lanā fī ṣāʿinā wa fī muddinā.
“O Allah, bless our ṣāʿ and our mudd.”
A ṣāʿ and a mudd are measures of grain. He asked for blessing not in the amount but in the measure itself, so that the same quantity would go further.
The full narration
Narrated Anas bin Malik:I went along with the Prophet (ﷺ) to Khaibar so as to serve him. (Later on) when the Prophet (ﷺ) returned he, on seeing the Uhud mountain, said, "This is a mountain that loves us and is loved by us." Then he pointed to Medina with his hand saying, "O Allah! I make the area which is in between Medina's two mountains a sanctuary, as Abraham made Mecca a sanctuary. O Allah! Bless us in our Sa` and Mudd (i.e. units of measuring)
