Sahih Muslim 1271
Sahih Muslim · Book 15: The Book of Pilgrimage · It is recommended to kiss the black stone during circumambulation (Tawaf)
This hadith has been narrated on the authority of Sufyan with the same chain of transmitters (and the words are):
وَحَدَّثَنِيهِ مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ ، عَنْ سُفْيَانَ ، بِهَذَا الإِسْنَادِ قَالَ وَلَكِنِّي رَأَيْتُ أَبَا الْقَاسِمِ صلى الله عليه وسلم بِكَ حَفِيًّا . وَلَمْ يَقُلْ وَالْتَزَمَهُ .
" That he ('Umar) said: But I saw Abu'l-Qasim (way peace be upon him) having great love for you." And he did not mention about clinging to it.
