Sahih al-Bukhari · Book 25: Hajj (Pilgrimage) · Whoever pointed towards the Corner (Black Stone)
Narrated Ibn `Abbas:
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا عَبْدُ الْوَهَّابِ ، حَدَّثَنَا خَالِدٌ ، عَنْ عِكْرِمَةَ ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ طَافَ النَّبِيُّ صلى الله عليه وسلم بِالْبَيْتِ عَلَى بَعِيرٍ، كُلَّمَا أَتَى عَلَى الرُّكْنِ أَشَارَ إِلَيْهِ.
The Prophet (ﷺ) performed Tawaf of the Ka`ba while riding a camel, and whenever he came in front of the Corner, he pointed towards it (with something).
