Mishkat al-Masabih, 2571

Abut Tufail said he saw God’s messenger going round the House, touching the corner with a crooked stick which he had, and kissing the crooked stick. Muslim transmitted it.

وَعَنْ أَبِي الطُّفَيْلِ قَالَ: رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَطُوفُ بِالْبَيْتِ وَيَسْتَلِمُ الرُّكْنَ بِمِحْجَنٍ مَعَهُ ويقبِّلُ المحجن. رَوَاهُ مُسلم
