Muwatta Imam Malik Book of Madina, Hadith 1

Yahya ibn Yahya related to me from Ishaq ibn Abdullah ibn Abi Talha al-Ansari from Anas ibn Malik that the Messenger of Allah ﷺ said, "O Allah! Bless them in their measure, and bless them in their sa and mudd." He meant the people of Madina.

وَحَدَّثَنِي يَحْيَى بْنُ يَحْيَى، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ الأَنْصَارِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " اللَّهُمَّ بَارِكْ لَهُمْ فِي مِكْيَالِهِمْ وَبَارِكْ لَهُمْ فِي صَاعِهِمْ وَمُدِّهِمْ " . يَعْنِي أَهْلَ الْمَدِينَةِ .
