The Messenger of Allah ﷺ said during the Farewell Pilgrimage, "Indeed, the most sacred of days is this day of yours. Indeed, your blood and your property are sacred to one another, like the sanctity of this day of yours, in this month of yours, in this land of yours. Have I conveyed the message?"They replied, "Yes."He said, "O Allah, bear witness."
قال رسول الله ﷺ في حجة الوداع: ألا إن أحرم الأيام يومكم هذا، ألا وإن دماءكم وأموالكم عليكم حرام كحرمة يومكم هذا في شهركم هذا، في بلدكم هذا، ألا هل بلغت؟ قالوا: نعم. قال: اللهم اشهد.
