He went to the Prophet and said: `Messenger of Allah, Fatima Bint Muhammad gave me this necklace and said: `Sell it, for Allah will grant you a solution to your problem.' When the Prophet (S) heard what the man had to say, he cried and said: `Indeed, Allah will grant you a solution, for Fatima Bint Muhammad, the Mistress of all women gave you this necklace.' Meanwhile, Ammar Ibn Yasir (may Allah bless his soul) said: `Messenger of Allah, do I have your permission to buy this necklace?' The Prophet (S) answered: `Buy it Ammar, surely if all of mankind and Jinn participate in buying it Allah will not torture them in Hellfire.' Ammar said: `How much do you want for it?' The old Beduin said: A meal of bread and meat, a Yemeni shirt to cover my private parts and to perform my prayers in front of my Lord, and a dinar so I can return to my family.' Ammar, who had just sold his share of booty from the battle of Khaibar, told the man: I will give you twenty (20) dinars, two hundred (200) dirhams, a Yemeni shirt, my horse to take you home, and your need of wheat bread and meat.' The old then said: `What a generous man you are!!' When Ammar had fulfilled his promise to the old man, the later came back to the Prophet (S) who said: Are you satisfied and clothed?' The old man said: Yes, and I have become rich; may my father and mother be your sacrifice.' The Prophet (S) then said: `So, reward Fatima for her kindness.' The old man supplicated: `O Allah, surely You are our God whenever we ask You; `We have no other God to worship besides you; 'You are the one who grants us beneficence in all conditions;' `O Allah, grant Fatima that which no eye has ever seen, and ear has ever heard ....' During that time, Ammar had perfumed the necklace with mush wrapped it in a Yemeni shirt, and gave it to one of his slaves by the name of Sahm, who he had bought with the money that he had received for selling his share of the Khaibarian booty.
He told Sahm: `Take this necklace and give it to the Messenger of Allah (S) and tell him that I give you to him also.' When Sahm had delivered the message, the Prophet (S) said: `Take the necklace to Fatima and I give you to her also.' When the slave had told Fatima the message, she (sa) took the necklace and told the slave that he was free. Upon hearing Fatima az-Zahra (sa), Sahm laughed, so Fatima az-Zahra (sa) asked him about the reason that made him laugh.
