I said to Abī ‘Abdillāh (Imam Sādiq (a.s.)): Sometimes when we are in Makkah, Madīnah, Ḥā`ir, or any other sacred place and we are sitting in a specific spot, we have to leave our spot to perform Wuďū, and while we are gone, someone else comes and sits in our spot. Imam (a.s.) replied, “Those who arrive first at a (particular) spot have more right to that spot than others for that entire day and night.”
