Musnad Abu Ya'la al-Mawsili 129:63

Abu Khaythama narrated to us, Mu'adh ibn Mu'adh al-'Anbari narrated to us, Humayd narrated to us, from Anas, who said: The Emigrants said, "O Messenger of Allah, we have not seen the likes of a people we have come to who are better in generosity when they have much, and better in consolation when they have little. They have spared us the burden and have made us partners in the pleasant things, and we fear that they will take all the reward." The Messenger of Allah (peace and blessings of Allah be upon him) said, "No, as long as you praise them and pray to Allah for them."
