I heard the Messenger of Allah ﷺ say, "The Amra has entered into the Hajj until the Day of Resurrection." He said, and the Messenger of Allah ﷺ combined Hajj and Amra in the Farewell Pilgrimage.
حدثنا مكي بن إبراهيم حدثنا داود يعني ابن يزيد قال سمعت عبد الملك الزراد يقول سمعت النزال بن سبرة صاحب علي يقول سمعت
سمعت رسول الله ﷺ يقول دخلت العمرة في الحج إلى يوم القيامة قال وقرن رسول الله ﷺ في حجة الوداع
Its chain is hasan. Dawud bin Yazid Awdi is daif, but his hadith becomes hasan when a trustworthy narrator reports from him, as Ibn Adi said, and what should we say when the one who reported from him is a firmly reliable trustworthy narrator, namely Makki bin Ibrahim. As for Abdul-Malik Zarrar, he is Ibn Maysara Hilali, and he is trustworthy, his hadith being accepted by the community of scholars. Nazal bin Sabra is among the great trustworthy narrators of the Followers, and it is said he had companionship with the Prophet. The hadith has already appeared at 17512.
