One day, meat was brought to the Messenger of Allah ﷺ, and the foreleg was offered to him, for it was the cut he favored. He then mentioned the long hadith of intercession, in which it was said,"I will say, 'My Lord, my Ummah, my Ummah!' It will be said, 'Muhammad, admit into Paradise those of your Ummah who will face no reckoning through the right gate of the gates of Paradise, though they will share with the rest of the people the other gates as well. By the One in whose hand is the soul of Muhammad, the distance between the two panels of any of the gates of Paradise is like the distance between Makkah and Hajar, or between Makkah and Busra.'"
أتي رسول الله ﷺ يوما بلحم، فرفع إليه الذراع، وكانت تعجبه، فذكر حديث الشفاعة الطويل، وجاء فيه: فأقول: يا رب، أمتي أمتي، فيقال: يا محمد، أدخل الجنة من أمتك من لا حساب عليه من الباب الأيمن من أبواب الجنة، وهم شركاء الناس فيما سوي ذلك من الأبواب، والذي نفس محمد بيده، إن ما بين المصراعين من مصاريع الجنة لكما بين مكة وهجر، أو كما بين مكة وبصرى.
Bukhari narrated it in the tafsir (4712), and Muslim in the faith (194), both through Abu Hayan Taymi, from Abu Zura bin Amr bin Jareer, from Abu Hurairah, who said, and then he related it. The wording given is that of Muslim, and Bukhari's wording is similar.
