صحيح البخاري#1608Sahihوَقَالَ مُحَمَّدُ بْنُ بَكْرٍ أَخْبَرَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي عَمْرُو بْنُ دِينَارٍ، عَنْ أَبِي الشَّعْثَاءِ، أَنَّهُ قَالَ وَمَنْ يَتَّقِي شَيْئًا مِنَ الْبَيْتِ، وَكَانَ مُعَاوِيَةُ يَسْتَلِمُ الأَرْكَانَ، فَقَالَ لَهُ ابْنُ عَبَّاسٍ ـ رضى الله عنهما ـ إِنَّهُ لاَ يُسْتَلَمُ هَذَانِ الرُّكْنَانِ. فَقَالَ لَيْسَ شَىْءٌ مِنَ الْبَيْتِ مَهْجُورًا، وَكَانَ ابْنُ الزُّبَيْرِ ـ رضى الله عنهما ـ يَسْتَلِمُهُنَّ كُلَّهُنَّ.
Abu Ash-Sha'tha said, "Who keeps away from some portion of the Ka'bah?" Mu'awiya used to touch the four corners of the Ka'bah, Ibn 'Abbas said to him, "These two corners (the one facing the Hijr) are not to be touched." Mu'awiya said, "Nothing is untouchable in the Ka'bah." And Ibn Az-Zubair used to touch all the corners of the Ka'bah

Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
