Harmalah bin Amr says that I participated in the Farewell Pilgrimage sitting behind my uncle Hazrat Sinan bin Sanah (may Allah be pleased with him). When we stood in the plain of Arafat, I saw the Prophet Muhammad (peace be upon him) that he had placed one finger over the other. I asked my uncle, "What is the Prophet (peace be upon him) saying?" He replied that the Prophet (peace be upon him) is saying: "To throw pebbles at the Jamarat like the pieces of a date stone, or pebbles like this."
