Allah Almighty says "O prophet, inform your wives and daughters". Did the prophet have daughters other than…

Answer

In the name of Allah, there is no doubt that the stepdaughter in the society’s custom is referred to as a daughter. Furthermore, if there is a person responsible for the people, then he considers all the women of the people his daughters even if the rulings of the real daughter are applied like the forbiddingness to marry and the like. Since the prophet (PBUH&HF) said "I and Ali are the fathers of this nation", this means they are responsible for its affairs and administration. Therefore, He says of the women believers as daughters of the prophet (PBUH&HF) as well as the stepdaughters. Allah is the Guide.
