Is it permissible for a woman to perform tawaf and sa'y without a mahram?

Question : What appears to me from her question is that she says she entered the state of ihram with her mahram from the miqat, and when they arrived in Makkah, the mahram was tired, so he did not perform the 'Umrah, while she was energetic, so she performed

Answer : the 'Umrah, and there is nothing wrong with this, because a woman is permitted to perform tawaf alone and sa'y alone, even if she does not have a mahram with her, because she is in the city and not a traveler, and she is also safe because there are many people around her, so there is no blame on the woman for making up her 'Umrah or performing tawaf, even if she does not have a mahram with her
