al-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”.

Ahmad reports from Jaabir ibn ‘Abdullaah that the Messenger of Allah (saw) said, concerning the Jews: “I am going to ask them about the soil of Paradise, which is a fine white powder.” So he asked them, and they said, “It is like a loaf of bread, O Abul-Qaasim,” The Messenger of Allah (saw) said, “Bread is like pearls”. [an-Nihaayah, 2/242]

Ahmad at-Tirmidhi and ad-Daarimi reported that the Prophet (saw) said, “I asked “O Messenger of Allah (saw), From what are people made?” He said, “From water.” We asked, “From what is Paradise built?” He said, “Bricks of gold and silver and mortar of fragrant musk; its pebbles are pearls and rubies, and its soil is saffron. Whoever enters it is blessed with joy and will never be miserable; he will remain there forever and never die; his clothes will never wear out, and his youth will never fade away .” [Mishkaat al-Masaabeeh, 3/89, no. 5630]
