The Book of Pilgrimage (Kitab Al-Hajj)
Muslim :: Book 7 : Hadith 3171
Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (may peace be upon him) was given the first fruit and he said: O Allah, shower blessings upon us in our city, and in our fruits, in our mudd and in our sa's, blessings upon blessings, and he would then give that to the youngest of the children present there.
