Messenger of Allah ﷺ said, "O Allah! Bestow Your Blessings on their measures, and bestow Your Blessings on their Sa' and Mudd." He meant those of the people of Medina.

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ اللَّهُمَّ بَارِكْ لَهُمْ فِي مِكْيَالِهِمْ وَبَارِكْ لَهُمْ فِي صَاعِهِمْ وَمُدِّهِمْ يَعْنِي أَهْلَ الْمَدِينَةِ
