Hadith 8:1709
Abu Bakr narrated to us, he said: Waki’ narrated to us, from Ibn Abi Layla, from ‘Ata, from Ibn ‘Abbas and Ibn ‘Umar, that they both disliked that soil from the Haram be taken out to the Hill (the area outside the sanctuary), or that soil from the Hill be brought into the Haram.
حدثناأبو بكر قال حدثنا وكيع عن بن أبي ليلى عن عطاء عن بن عباس وبن عمر أنهما كرها أن يخرج من تراب الحرم إلى الحل أو يدخل من تراب الحل إلى الحرم
