Shaykh Saalih Ibn Fawzaan al-Fawzaan says, “Shirk is to designate an associate/partner (shareek) with Allaah in His Ruboobiyyah (Lordship), or His Uloohiyyah (Divinity). In most cases, the association (ishraak) is in the uloohiyyah, by calling upon someone along with Allaah, or designating for other than Allaah something from the various types of worship such as: sacrifice, taking oaths, and fear, and hope, and love
