Musnad `Umar b. al-Khattab (ra)
حَدَّثَنَا أَبُو مُعَاوِيَةَ، حَدَّثَنَا عَاصِمٌ الْأَحْوَلُ، عَنْ عَبْدِ اللَّهِ بْنِ سَرْجِسَ، قَالَ رَأَيْتُ الْأُصَيْلِعَ يَعْنِي عُمَرَ رَضِيَ اللَّهُ عَنْهُ يُقَبِّلُ الْحَجَرَ وَيَقُولُ إِنِّي لَأُقَبِّلُكَ وَأَعْلَمُ أَنَّكَ حَجَرٌ لَا تَنْفَعُ وَلَا تَضُرُّ وَلَوْلَا أَنِّي رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُقَبِّلُكَ لَمْ أُقَبِّلْكَ.
