"We went out with the Messenger of Allah around the time of the new moon of Dhul-Hijjah, and the Messenger of Allah said: 'Whoever wishes to enter Ihram for Hajj, let him do so , and whoever wishes to enter Ihram for 'Umrah, let him do so'" (Using translation from Nasāʾī 2717)
خَرَجْنَا مَعَ رَسُولِ اللهِ ﷺ مُوَافِينَ لِهِلَالِ ذِي الْحِجَّةِ فَقَالَ رَسُولُ اللهِ ﷺ «مَنْ شَاءَ أَنْ يُهِلَّ بِحَجٍّ فَلْيُهلِلْ وَمَنْ شَاءَ أَنْ يُهِلَّ بِعُمْرَةٍ فَلْيُهلِلْ بِعُمْرَةٍ»
