The Prophet of Allah, sallallaahu ‘alayhi wa sallam, visited them, ate at their homes, and guided them to the best ways of being charitable with their money

“Out of all the Ansaar in Madinah, Abu Talhah (a Companion) had the most date-palm trees, and the most beloved of his land was Bayrahaa’, a piece of land that faces the mosque. The Messenger of Allah, sallallaahu ‘alayhi wa sallam, used to enter it and drink from some water therein. When the verse (which means): «Never will you attain the good [reward] until you spend [in the way of Allah] from that which you love.» [Quran: 3:92] was revealed, Abu Talhah stood and said to the Messenger of Allah, sallallaahu ‘alayhi wa sallam, ‘O Messenger of Allah, Allah Says (what means): «Never will you attain the good [reward] until you spend [in the way of Allah] from that which you love.» and the most beloved part of my wealth is Bayruhaa’. Therefore, it is a charity for the sake of Allah, and I hope that Allah accepts it and stores it for me in my record of good deeds, so use it in any way Allah shows you (any way you see fit).’

‘I shall do so, O Messenger of Allah.’ So Abu Talhah divided it between his relatives and cousins, and among them were Hassaan and Ubayy ibn Ka`b.”
