When my sister became ill, my paternal grandmother vowed that if my sister recovered, she would take her to visit
Al-Masjid Al-Nabawy Al-Sharif (the Prophet’s Mosque in Madinah).
However, my grandmother died
before fulfilling her vow (may Allah have mercy on her). Should I take my sister to visit
Al-Masjid Al-Nabawy Al-Sharif
to fulfill my late grandmother’s vow, In sha’a-Allah (if Allah wills)? If this is not permissible, what should I do? Please advise concerning this. As-salamu ‘alaykum warahmatullah wabarakatuh (May Allah’s Peace, Mercy, and Blessings be upon you!)
There is nothing wrong in taking your sister to visit
Al-Masjid Al-Nabawy after her recovery to fulfill your grandmother’s vow, as it is a vow to do an act of obedience. It was authentically reported from the Prophet (peace be upon him) that he said:
A person who vows to obey Allah should do so.
May Allah grant us success! May peace and blessings be upon our Prophet Muhammad, his family and Companions!
