It was narrated that 'Abis bin Rabee'ah said:

I saw 'Umar look at the Black Stone and say: By Allah, were it not that I saw the Messenger of Allah ﷺ kiss you, I would not have kissed you. Then he kissed it.

حَدَّثَنَا أَسْوَدُ بْنُ عَامِرٍ، قَالَ حَدَّثَنَا زُهَيْرٌ، عَنْ سُلَيْمَانَ الْأَعْمَشِ، حَدَّثَنَا إِبْرَاهِيمُ، عَنْ عَابِسِ بْنِ رَبِيعَةَ، قَالَ رَأَيْتُ عُمَرَ نَظَرَ إِلَى الْحَجَرِ فَقَالَ أَمَا وَاللَّهِ لَوْلَا أَنِّي رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُقَبِّلُكَ مَا قَبَّلْتُكَ ثُمَّ قَبَّلَهُ‏.‏
