Hadith 8:1151
Abu Bakr narrated to us, he said: Ibn ‘Isa narrated to us, from Khalid ibn Abi Bakr, he said: I saw ‘Ubayd Allah ibn ‘Abd Allah embracing the back of the Ka‘bah from the side that faces the west, pressing his chest against it.
حدثنا أبو بكر قال حدثنا بن عيسى عن خالد بن أبي بكر قال رأيت عبيد الله بن عبد الله يلتزم خلف الكعبة مما يلي المغرب يلصق بها صدره
