Sahih Bukhari Volume 3, Book 54, Hadith 2720

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، حَدَّثَنَا أَبُو الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَتِ الأَنْصَارُ لِلنَّبِيِّ صلى الله عليه وسلم اقْسِمْ بَيْنَنَا وَبَيْنَ إِخْوَانِنَا النَّخِيلَ‏.‏ قَالَ ‏"‏ لاَ ‏"‏‏.‏ فَقَالَ تَكْفُونَا الْمَئُونَةَ وَنُشْرِكُكُمْ فِي الثَّمَرَةِ‏.‏ قَالُوا سَمِعْنَا وَأَطَعْنَا‏.‏

Narrated By Abu Huraira : The Ansar said to the Prophet, "Divide our date-palms between us and our emigrant brothers." The Prophet said, "No." The Ansar said to the emigrants, "You may do the labour (in our gardens) and we will share the fruits with you." The emigrants said, "We hear and obey."
