مختصر صحيح بخاري
Mukhtasar Sahih Bukhari
Book of Beginning of Creation
What is narrated about Paradise and that it is already created.
Narrated Anas bin Malik (may Allah be pleased with him): A cloak made of sundus (silk cloth) was brought to the Prophet (peace and blessings of Allah be upon him), and he used to forbid the use of silk cloth. The people began to admire it. The Prophet (peace and blessings of Allah be upon him) said: "By Him in Whose hand is the life of Muhammad (peace and blessings of Allah be upon him), the handkerchiefs of Sa'd bin Mu'adh (may Allah be pleased with him) in Paradise are better than this."
