عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَسْتَلِمُ الْحَجَرَ الْأَسْوَدَ فَلَا أَدَعُ اسْتِلَامَهُ فِي شِدَّةٍ وَلَا رَخَاءٍ
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both), he says: I saw the Messenger of Allah (peace and blessings be upon him) touching the Black Stone; whether there is a crowd or not, I will not abandon touching it.
