Musnad Ahmad 1153:2008

Yazid narrated to us, he said: Shu'bah ibn al-Hajjaj informed us, from Abu 'Imran al-Jawni, from Talhah, a man from Quraysh, from 'Aishah, she said: I said, "O Messenger of Allah, I have two neighbors, so to which of them should I give a gift?" He said, "To the one of them whose door is closest to you."
