It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that on the occasion of the Farewell Pilgrimage, the Prophet (peace and blessings be upon him) passed through the valley of ‘Usfan. He (peace be upon him) asked Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him):“O Abu Bakr! Which valley is this?”He replied:“The valley of ‘Usfan.”The Prophet (peace be upon him) said:“From here, Prophet Hud and Prophet Salih (peace be upon them) passed on red, young camels whose reins were made of palm fiber. Their lower garments were cloaks, and their upper sheets were made of leopard skins, and they were reciting the Talbiyah as they went for Hajj to the House of Allah.”
