Is it true that Abu Bakr granted Aisha a plot of land, then Umar returned the land to Abu Bakr's estate and prevented Aisha from having it? And does this constitute a deprivation of Aisha's right?

The story recounts that Abu Bakr Al-Siddiq, may Allah be pleased with him, gifted his daughter Aisha twenty wasqs of dates, but she did not take possession of them. When his death was imminent, he said to her: "Had you taken possession and seized them, they would have been yours. But today, they are the property of the heirs." The story also mentions that Abu Bakr said to Aisha, "Indeed, they are your two brothers and your two sisters." Aisha asked him, "Asmaa is one, so who is the other?" He replied, "The one in the womb of Kharijah's daughter, I believe she is a girl." Scholars have derived several benefits from this story, among them: that a gift is not valid unless it is taken possession of before the death of the giver, and that richness is more beloved to the virtuous than poverty.
