Sahih Muslim , Book 7, Hadith 3076 (USC-MSA) ⓘ
Ibn Abbas (Allah be pleased with them) reported that Allah's Apostle entered the Ka'ba, and in it there were six pillars, and he stood near a pillar and made supplication, but did not observe the prayer.
حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا عَطَاءٌ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم دَخَلَ الْكَعْبَةَ وَفِيهَا سِتُّ سَوَارٍ فَقَامَ عِنْدَ سَارِيَةٍ فَدَعَا وَلَمْ يُصَلِّ .
