The Messenger of Allah ﷺ performed four umrahs, all of them in Dhul-Qadah, except for the one that accompanied his Hajj. The first was the umrah of Hudaybiyah in Dhul-Qadah, the second was the umrah of the following year in Dhul-Qadah, the third was the umrah from Jiranah, where he distributed the spoils of Hunayn, in Dhul-Qadah, and the fourth was the umrah performed with his Hajj.
اعتمر رسول الله ﷺ أربع عمر، كلهن في ذي القعدة، إلا التي كانت مع حجته: عمرة من الحديبية في ذي القعدة، وعمرة من العام المقبل في ذي القعدة، وعمرة من الجعرانة، حيث قسم غنائم حنين في ذي القعدة، وعمرة مع حجته.
