Bukhaari and Muslim reported the hadith of al-Mi'raaj from Anas ibn Maalik from Abu Dharr in which Abu Dharr (ra) said, "The Messenger of Allah (saw) said, "I entered Paradise where I saw lights of pearl and its soil was musk". Muslim and Ahmad report from Abu Sa'eed that Ibn Sayyaad asked the Messenger (saw) about the soil of Paradise. He said, "It is a fine white powder of pure musk".
