Sahih al-Bukhari Book 63, Hadith 17 Next Hadith → That he heard Anas bin Malik when he went with him to Al-Walid, saying, "Once the Prophet (ﷺ) called the Ansar in order to give them the territory of Bahrain they said, 'No, unless you give to our emigrant brethren a similar share.' On that he said 'If you do not agree to it, then be patient till you meet me, for after me others will be given preference to you."'
