عَنْ سَالِمٍ عَنْ أَبِيهِ أَنَّهُ قَالَ: لَمْ أَرَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَمْسَحُ مِنَ الْبَيْتِ إِلَّا الرُّكْنَيْنِ الْيَمَانِيَّيْنِ
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both), he says: I saw that the Messenger of Allah (peace and blessings be upon him) used to perform istilam (touching or kissing) of only the two Yemeni corners of the Ka'bah (i.e., Rukn Yamani and Hajar Aswad).
