He performed Hajj with the Prophet ﷺ on the day he drove the sacrificial animals along with him, and the people had entered ihram intending Hajj alone. The Prophet ﷺ said to them, "Exit your ihram by performing tawaf around the House and saʿy between Safa and Marwa, then shorten your hair and remain in a non-consecrated state. When the day of Tarwiyah arrives, enter ihram for Hajj, and treat the one you arrived with as tamattu."They asked, "How can we make it tamattu when we have already declared it as Hajj?"He replied, "Do as I have commanded you. Had I not brought the sacrificial animals with me, I would have done the same as I have ordered you to do. But nothing forbidden becomes lawful for me until the sacrificial animal reaches its place of slaughter."So they did as he instructed.
أنه حج مع النبي ﷺ يوم ساق البدن معه وقد أهلوا بالحج مفردا، فقال لهم: أحلوا من إحرامكم بطواف البيت وبين الصفا والمروة، وقصروا، ثم أقيموا حلالا حتى إذا كان يوم التروية فأهلوا بالحج واجعلوا التي قدمتم بها متعة، فقالوا: كيف نجعلها متعة وقد سمينا الحج؟ فقال: افعلوا ما أمرتكم، فلولا أني سقت الهدي لفعلت مثل الذي أمرتكم، ولكن لا يحل مني حرام حتى يبلغ الهدي محله ففعلوا.
Bukhari narrated it in Hajj (1568) and Muslim in Hajj (1216/143), both from the hadith of Abu Naeem (who is Fadl bin Dukayn), who said, our teacher Abu Shihab told us, he said, "I came to Makkah for umrah, and we entered three days before Tarwiya. Some people of Makkah said to me, 'Your hajj will become a Makkan one.' So I went in to Ata to ask him for a ruling, and he said, Jabir bin Abdullah told me," and he related it in full.In another version with Bukhari (1651), through the route of Habib al-Muallim, from Ata, with the same chain, the wording is, "So the Prophet ﷺ commanded his companions to make it an umrah, to perform tawaf, then to trim their hair and end their state of ihram, except for anyone who had brought a sacrificial animal with him..."
