Nafi reported,

Whenever Ibn Umar رضي الله عنهم intended to set out for Makkah, he would apply oil that had no fragrance, then come to the mosque of Dhul-Hulayfah and pray. He would then mount his camel, and once it stood upright with him on it, he would enter the state of ihram. He said, "This is how I saw the Prophet ﷺ do it."

Sahih

عن نافع، قال

كان ابن عمر رضي الله عنهما إذا أراد الخروج إلى مكة ادهن بدهن ليس له رائحة طيبة، ثم يأتي مسجد ذي الحليفة فيصلي، ثم يركب وإذا استوت به راحلته قائمة أحرم ثم قال: هكذا رأيت النبي ﷺ فعل.
