Hadith 8:171
Abu Bakr narrated to us, he said: Ibn Fudayl narrated to us, from ‘Ata’ ibn al-Sa’ib, from Tawus, from Ibn ‘Abbas, he said: Circumambulating the House (the Ka’bah) is prayer, but Allah has permitted speech within it. So whoever speaks, let him not speak except with good.
حدثنا أبو بكر قال ثنا بن فضيل عن عطاء بن السائب عن طاوس عن بن عباس قال الطواف بالبيت صلاة ولكن الله أحل فيه المنطق فمن نطق فلا ينطق إلا بخير
