Is the husband obliged to take his fifty-year-old mother-in-law, who wishes to perform Hajj, knowing that there is no one else to accompany her as a mahram except him, and that he fears this will affect his enjoyment of Hajj, while at the same time he does not want to deprive her of performing the obligation for which she has saved money?

We advise you to register this woman with you and take her with you on the Hajj journey to help her fulfill her obligation. For this, you will receive a multiplied reward, for Allah helps His servant as long as the servant helps his brother. This will not diminish your enjoyment of Hajj, as it is possible to perform Tawaf, pray, and remember Allah while she is in her lodging, after performing the obligatory Tawaf and Sa'i with her. Allah will facilitate your affairs for what you do in helping this needy woman.
