Is the thing her daughter found in her bathroom on her wedding morning the reason for the delay in her pregnancy?

It cannot be definitively asserted that magic exists, and ruqyah شرعية (Islamic exorcism/healing) is prescribed for those afflicted and others. There is no harm in continuing treatment with a raqi (healer) known for his effectiveness and uprightness. Psychological and medical websites can be consulted, with caution against charlatans. Do not accuse anyone of magic without clear proof. Objects feared to contain magic should be disposed of by burning them.
