Hazrat Abu Hurairahra relates that the Holy Prophetsa used to offer this prayer on seeing a new fruit:
اَللّٰهُمَّ بَارِكْ لَنَا فِى ثَمَرِنَا وَبَارِكْ لَنَا فِى مَدِينَتِنَا وَبَارِكْ لَنَا فِى صَاعِنَا وَبَارِكْ لَنَا فِى مُدِّنَا
“O Allah, bless our fruits, bless our city for us and bestow blessings on the bowls with which we measure our grain.”
(Sahih Muslim, Kitab al-Hajj)
