Sahih Bukhari Volume 3, Book 47, Hadith Number 773.
Narated By Jabir bin ‘Abdullah : My father was martyred on the day (of the battle) of Uhud and his creditors demanded the debt back in a harsh manner. So I went to Allah’s Apostle and informed him of that, he asked them to accept the fruits of my garden and excuse my father, but they refused. So, Allah’s Apostle did not give them the fruits, nor did he cut them and distribute them among them, but said, “I will come to you tomorrow morning.” So, he came to us the next morning and walked about in between the date-palms and invoked Allah to bless their fruits. I plucked the fruits and gave back all the rights of the creditors in full, and a lot of fruits were left for us. Then I went to Allah’s Apostle, who was sitting, and informed him about what happened. Allah’s Apostle told ‘Umar, who was sitting there, to listen to the story. ‘Umar said, “Don’t we know that you are Allah’s Apostle? By Allah! you are Allah’s Apostle!”
