"Since I saw the Messenger of Allah touch it, I did not fail to touching the Stone whether it was easy or difficult." (Using translation from Nasāʾī 2953)   

مَا تَرَكْتُ اسْتِلَامَ الرُّكْنَيْنِ فِي شِدَّةٍ وَلَا رَخَاءٍ مُنْذُ رَأَيْتُ رَسُولَ اللهِ ﷺ يَسْتَلِمُهُمَا الْحَجَرَ وَالرُّكْنَ الْيَمَانِيَ  

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»
