← Previous 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."'

Sahih al-Bukhari Book 63, Hadith 19 Next Hadith → On the day of the battle of the Trench (i.e. Ghazwat-ul-Khandaq) the Ansar used to say, "We are those who have given the pledge of allegiance to Muhammad for Jihad (i.e. holy fighting) as long as we live." The Prophet (ﷺ) , replied to them, "O Allah! There is no life except the life of the Hereafter; so please honor the Ansar and the Emigrants."
