وَعَنْ عُمَرَ رضى الله عنه
«أَنَّهُ قَبَّلَ اَلْحَجَرَ فَقَالَ: إِنِّي أَعْلَمُ أَنَّكَ حَجَرٌ لَا تَضُرُّ وَلَا تَنْفَعُ، وَلَوْلَا أَنِّي رَأَيْتُ رَسُولَ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُقَبِّلُكَ مَا قَبَّلْتُكَ»
Umar (RAA) narrated that he kissed the Black Stone and said, ‘I know that you are a stone and can neither benefit anyone nor harm anyone. Had I not seen the Messenger of Allah (sallallahu alayhi wa sallam) kissing you, I would not have kissed you.’ Agreed upon.
