The Messenger of Allah ﷺ performed four Umras, all of them in Dhul-Qadah, except for the one that was joined with his Hajj. The first was the Umra of Hudaybiya in Dhul-Qadah, the second was the Umra of the following year in Dhul-Qadah, the third was the Umra from Jiranah, when he distributed the spoils of Hunayn, in Dhul-Qadah, and the fourth was the Umra 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.
