Ibn ʿUmar. said, "I have never missed the touching of these two stones of Kaʿba (the Black Stone and the Yemenite Corner) both in the presence and the absence of crowds, since I saw the Prophet ﷺ touching them." I asked Nafiʿ: "Did Ibn ʿUmar use to walk between the two Corners?" Nafiʿ replied, "He used to walk in order that it might be easy for him to touch it (the Corner Stone)." (Using translation from Bukhārī 1606)  

«مَا تَرَكْتُ اسْتِلَامَ هَذَيْنِ الرُّكْنَيْنِ فِي شِدَّةٍ وَلَا رَخَاءٍ مُنْذُ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَسْتَلِمُهُمَا» قُلْتُ لِنَافِعٍ أَكَانَ ابْنُ عُمَرَ يَمْشِي بَيْنَ الرُّكْنَيْنِ؟ قَالَ «إِنَّمَا كَانَ يَمْشِي لِيَكُونَ أَيْسَرَ لِاسْتِلَامِهِ»
