"I saw Umar bin Al-Khattab kissing the (Black) Stone and saying: 'I am kissing you while I know that you are just a stone, and if I had not seen the Messenger of Allah kissing you, I would not kiss you.'"
رَأَيْتُ عُمَرَ بْنَ الْخَطَّابِ يُقَبِّلُ الْحَجَرَ وَيَقُولُ إِنِّي أُقَبِّلُكَ وَأَعْلَمُ أَنَّكَ حَجَرٌ وَلَوْلاَ أَنِّي رَأَيْتُ رَسُولَ اللَّهِ ﷺ يُقَبِّلُكَ لَمْ أُقَبِّلْكَ قَالَ وَفِي الْبَابِ عَنْ أَبِي بَكْرٍ وَابْنِ عُمَرَ
