Is a believer obligated to adhere to what he sees in his dream, whether it is for him or for someone else, and does the matter differ if more than one person saw it, or if the vision was repeated for the same person?

A dream does not necessitate acting upon it, even if it recurs. A believer must put their trust in Allah and have faith in His divine decree and destiny. Naming a newborn Ibraheem is permissible, and the Prophet, peace and blessings be upon him, named his son by this name.
