Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: When people would see the first fruit, they would bring it to the service of the Prophet Muhammad (peace and blessings be upon him). The Prophet (peace and blessings be upon him) would take it and make this supplication: "O Allah! Put blessing for us in our fruits, put blessing for us in our city, put blessing for us in our sa‘ and our mudd. O Allah! Indeed, Sayyiduna Ibrahim (peace be upon him) was Your servant and Your prophet, and I am also Your servant and Your prophet. He prayed to You for Makkah, and I pray to You for Madinah for the like of what he prayed for Makkah, and along with it, as much more in addition." Then the Prophet (peace and blessings be upon him) would call the youngest child present there and give him that fruit.
