The story of Umm Shuraik:
Imâm al-Baihaqî related on the authority of Abû Hurairah who said: “There was a woman from the tribe of Doas called Umm Shuraik who embraced Islâm in Ramadân”. Abû Hurairah mentioned the story of her migration to Madînah, accompanied by a Jewish man. On the way, she became thirsty, but he refused to give her water unless she embraced Judaism. She fell asleep and saw in her dreams that someone was giving her water, and when she woke up she felt that she has quenched her thirst. When she came to the Nabi Pakﷺ she told him her story, and he asked her for marriage, but she felt that she did not deserve to be the wife of the Nabi Pakﷺ and said to him: “But marry me to whoever you choose”. He married her to his slave Zaid Ibn Hârithah, and he ordered that 30 Sâ’ (a measure of capacity) of barley be given to her, and said to them: “Eat and do not re-measure the barley”. She also had some clarified butter in a small leather skin which she intended to give as a present to the Nabi Pakﷺ. She ordered her servant to carry it to him, and when she arrived there, she poured it all for him. He ordered her to hang it in its place, when she gets back (to Umm Shuraik) and not to tie it up. When Umm Shuraik came in, she found that the skin was full, so she asked her servant: “Didn’t I ask you to take it to the Messenger of Allâh ﷺ ? The servant assured her that she did. They mentioned what happened to the Nabi Pakﷺ and he ordered them not to tie it up. It remained there for a while, until Umm Shuraik tied it up, and when they measured the barley, they found that it was still 30 Sâ“”.
Another Hadîth reported by Jâbir:
Imâm Muslim reported on the authority of Jâbir that a man came to the Nabi Pakﷺ and asked for food. He gave him half a Wasq (measure) of barley, and the man and his wife and their guest kept on making use of it (as a food) until he weighed it (in order to find the actual quantity), but he found nothing left. He came to Allâh’s Messenger ﷺ and informed him about it. He said: “Had you not weighed it, you would be eating out of it and it would have remained intact for you “
