The personal account also mentions waiting for guidance from the unseen and compares the experience to istikhārah. The analogy expresses the author’s expectation of a fitting verse, divine name, or prayer within that reported experience; it is not a full definition of the commonly established devotional practice.
Istikhārah in ordinary religious usage means asking God to guide one toward what is good. It does not necessarily require a dream, a secret signal, or an extraordinary message.
A private account must therefore not be converted into a binding ritual method or a requirement that unseen communication will occur.
