مُسْنَدُ أَحْمَدَ
Musnad Ahmad 381
Musnad `Umar b. al-Khattab (ra)
حَدَّثَنَا وَكِيعٌ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، أَنَّ عُمَرَ، رَضِيَ اللَّهُ عَنْهُ أَتَى الْحَجَرَ فَقَالَ إِنِّي لَأَعْلَمُ أَنَّكَ حَجَرٌ لَا تَضُرُّ وَلَا تَنْفَعُ وَلَوْلَا أَنِّي رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُقَبِّلُكَ مَا قَبَّلْتُكَ قَالَ ثُمَّ قَبَّلَهُ.
It was narrated from Hisham, from his father, that `Umar (رضي الله عنه) came to the [Black] Stone and said: I know that you are only a stone and you cannot cause harm or bring benefit. Were it not that I saw the Messenger of Allah(ﷺ )kiss you, I would not have kissed you. Then he kissed it.
