Is Hajj waived for a woman if the presence of a mahram is not possible?

Question:
May Allah reward you with good. From the questioner's questions, he says: Honorable Shaykh, he says: Is the obligation of Hajj waived for a woman if she does not find a mahram? And if a woman performs Hajj with a group of women, is this correct?

Answer:
Hajj is not waived for her as long as she is able to perform Hajj with her money, finding what enables her to perform Hajj, for it is obligatory for her. But if there is no mahram and his presence is difficult to obtain, she appoints someone to perform Hajj on her behalf, acting as her substitute in performing Hajj. It is a condition for the substitute that he has first performed Hajj for himself. Hajj is not waived for her. If she performs Hajj without a mahram, she is sinful, but her Hajj is valid. If she performs its rites in the required manner, her Hajj is valid, but she is sinful for the absence of a mahram. A group of women is not sufficient; they do not suffice in place of a mahram. The Messenger (peace and blessings be upon him) said: "It is not permissible for a woman who believes in Allah and the Last Day to travel except with a mahram." When a man wanted to go out in the cause of Allah and informed the Prophet (peace and blessings be upon him) that his wife had gone out for Hajj, he said to him: "Go and perform Hajj with your wife."
