وَمِنْ ءَابَآئِهِمْ وَذُرِّيَّٰتِهِمْ وَإِخْوَٰنِهِمْ ۖ وَٱجْتَبَيْنَٰهُمْ وَهَدَيْنَٰهُمْ إِلَىٰ صِرَٰطٍۢ مُّسْتَقِيمٍۢ
With some of their forefathers and their offspring and their brethren; and We chose them and guided them unto a straight path.

Sahih al-Bukhari
Hajj (Pilgrimage)
Chapter: The purchase of Hadi on the way and garlanding it
Narrated Nafi`:
Ibn `Umar intended to perform Hajj in the year of the Hajj of Al-Harawriya during the rule of Ibn Az- Zubair. Some people said to him, "It is very likely that there will be a fight among the people, and we are afraid that they might prevent you (from performing Hajj)." He replied, "Verily, in Allah's Messenger (ﷺ) there is a good example for you (to follow). In this case I would do the same as he had done. I make you witness that I have intended to perform `Umra." When he reached Al-Baida', he said, "The conditions for both Hajj and `Umra are the same. I make you witness that I have intended to perform Hajj along with `Umra." After that he took a garlanded Hadi (to Mecca) which he bought (on the way). When he reached (Mecca), he performed Tawaf of the Ka`ba and of Safa (and Marwa) and did not do more than that. He did not make legal for himself the things which were illegal for a Muhrim till it was the Day of Nahr (sacrifice), when he had his head shaved and slaughtered (the sacrifice) and considered sufficient his first Tawaf (between Safa and Marwa), as a (Sa`i) for his Hajj and `Umra both. He then said, "The Prophet (ﷺ) used to do like that."
