What is the ruling on establishing a children's play café through which da'wah activities are practiced, despite feeling the difficulty of this and fearing the inability to do so, even though Istikhara prayer has been performed and prayer has been seen in dreams three times, one of which was in the Grand Mosque of Makkah?

Calling to Allah is an obligation upon every Muslim, and its means and methods vary according to circumstances. It must be done with wisdom and good admonition. If the recreational coffee shop for children adheres to the Sharia (definition) guidelines, then there is no objection to it, and it should be utilized for calling to Allah. Istikhara (seeking guidance from Allah) is a Sunnah (definition) before embarking on matters, and the appearance of its fruit does not necessitate a dream. A dream can be a source of comfort, but it is not obligatory to act upon its content.
