I got this story about Sayyidah Fatima's necklece from a shia source but was not able to find it anywhere else , if u guys know about it or have some reference from a sunni source then please let me know.. " Jabir ibn Abdullah al-Ansari, the Prophet's ﷺ companion, says that a poor emigrant (Muhajir) came to the Prophet ﷺ and asked for help. The Prophet ﷺ answered: "I do not have anything. Go to my daughter whose house is beside mine". Then Bilal رضي الله عنه the Prophet ﷺ muezzin, guided him. He went to Fatimah's رضي الله عنه house and said: "Peace be upon you, O The family of the Prophet!" and asked for help. When Fatimah ﷺ got aware of his poverty, although she and her father and husband did not have anything to eat for three days, she brought out the necklace which Hamzah's رضي الله عنه son -her cousin- had presented her and told the man: "Take this and sell it. I hope that Allah gives you better than this". The man took the necklace and went to the Prophet ﷺ and described what had happened. The Prophet ﷺ cried and prayed for him. Ammar Yasir رضي الله عنه stood up and after asking for permission, bought the necklace and gave him food, cloth, an animal and cost of travelling. The Prophet ﷺ asked the man: "Are you satisfied?" The man felt ashamed and thanked. Ammar put the necklace in a Yemeni cloth and perfumed it and dedicated it to the Prophet ﷺ with his slave. The slave came to the Prophet ﷺ and told the story. The Prophet ﷺ offered the necklace and the slave to Fatimah رضي الله عنه The slave came to Fatimah رضي الله عنه She took the necklace and let the slave free. Then the slave smiled and when he was asked for the reason, he answered: "What a blessed necklace! It fed a hungry, covered a naked, made a pedestrian have an animal, made someone free from want, let a slave free and finally returned to its owner".
