Musnad Ahmad Hadith 14409

It is narrated from Jabir (may Allah be pleased with him) that we, meaning the Companions (may Allah be pleased with them), had assumed Ihram only for Hajj, and we reached Makkah Mukarramah on the fourth of Dhul-Hijjah. The Prophet (ﷺ) ordered his Companions to consider it as Ihram for Umrah and to come out of the state of Ihram. Upon this, people began to say among themselves that when only five days are left for the day of Arafat, we are being ordered to come out of Ihram so that when we proceed towards Mina, impure drops will be dripping from our private parts. When the Prophet (ﷺ) came to know of this, he said: If that matter which came to me later had come to me earlier, I would not have brought the sacrificial animal with me, and if I did not have the Hadi (sacrificial animal) with me, I too would have come out of Ihram. So you come out of Ihram and make it Umrah. He further says that Ali (may Allah be pleased with him) came from Yemen, so the Prophet (ﷺ) asked him: With what intention did you assume Ihram? He said: With the same intention as the Prophet (ﷺ) assumed Ihram. The Prophet (ﷺ) said: Then remain in the state of Ihram as I am.
