Musnad Ahmad 33:141

Hushaym narrated to us, 'Abd al-Malik informed us, from 'Ata', from Jabir ibn 'Abd Allah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The neighbor is more entitled to the pre-emption (shuf'ah) of his neighbor; he is to be waited for, even if he is absent, if their path is one."
