Bakr reported,

I mentioned to Abdullah bin Umar that Anas had related that the Messenger of Allah ﷺ had pronounced the talbiyah for both umrah and hajj together.Ibn Umar said, "May Allah have mercy on Anas. He is mistaken. He is mistaken. We only set out with the Messenger of Allah ﷺ as pilgrims for hajj. When we arrived, he commanded us to convert it into an umrah, except for those who had brought sacrificial animals with them."The narrator said, "I then mentioned this to Anas, who became angry and said, 'You all consider us as nothing but children.'"

حدثنا محمد بن أبي عدي عن حميد

عن بكر قال

ذكرت لعبد الله بن عمر أن أنسا حدثه أن رسول الله ﷺ لبى بالعمرة والحج فقال ابن عمر يرحم الله أنسا وهل أنس وهل خرجنا مع رسول الله ﷺ إلا حجاجا فلما قدمنا أمرنا أن نجعلها عمرة إلا من كان معه هدي قال فحدثت أنسا بذلك فغضب وقال لا تعدونا إلا صبيانا
