Maymun bin Mihran reported,

I set out to perform Umrah during the year when the Syrian army besieged Ibn Zubayr in Mecca. Some men from my people sent a sacrificial animal with me. When we reached the Syrian forces, they prevented us from entering the sacred precinct, so I slaughtered the sacrificial animal where I was, exited my state of consecration, and returned home.The following year, I went out to make up my Umrah. I came to Ibn Abbas and asked him about it.He said, "Offer a replacement sacrifice, for the Messenger of Allah ﷺ commanded his companions to replace the sacrificial animals they had slaughtered during the year of Hudaybiyyah when they performed the make-up Umrah."

عن ميمون بن مهران قال

خرجت معتمرا عام حاصر فلما أهل الشام ابن الزبير بمكة، وبعث معي رجال من قومي بهدي، فلما انتهينا إلى أهل الشام منعونا أن ندخل الحرم، فنحرت الهدي مكاني، أحللت ثم رجعت، فلما كان من العام المقبل خرجت لأقضى عمرتي فأتيت ابن عباس فسألته فقال: أبدل الهدي فإن رسول الله ﷺ أمر أصحابه أن يبدلوا الهدي الذي نحروا عام الحديبية في عمرة القضاء.
