Ṭūbā (Arabic: طُوبَىٰ ṭūbā, lit. "blessedness"[1]) is a tree that Muslims believe grows in Jannah, or Islamic heaven.
The tree is only mentioned once in the Koran[2] but its attributes can be ascertained from various hadiths and other writings. Ṣaḥīḥ al-Bukhārī 4:474 notes that the tree spreads over a distance that can be covered in a hundred years and that the gowns of righteous dwellers of heaven are made from the fiber of its blossoms. A sage in Sohrevardi's The Red Intellect says that "any fruit you see in the world will be on that tree". The tree is sometimes described as being inverted and having its roots in the air. Mehmed Yazıcıoğlu (Yazıcızade, Yaziji-Oglu) wrote of the tree in "The Creation of Paradise" in his 1449 Book of Muhammad (Muhammediye):
In its courtyard's riven center, planted he the Tuba-Tree; That a tree which hangeth downward, high aloft its roots are there: Thus its radiance all the Heavens lighteth up from end to end, Flooding every tent and palace, every lane and every square. Such a tree the Tuba, that the Gracious One hath in its sap Hidden whatsoe'er there be of gifts and presents good and fair; Forth therefrom crowns, thrones, and jewels, yea, and steeds and coursers come, Golden leaves and clearest crystals, wines most pure beyond compare. For his sake there into being hath he called the Tuba-Tree, That from Ebu-Qasim's hand might every one receive his share.
— Mehmed Yazıcıoğlu, Book of Muhammad[3]
The holy city of Touba, Senegal is named for the tree.
The Arabic female given name Tuba or Touba derives from the tree. Tuba (often spelt "Tuğba") is also a modern Arabic borrowing into Turkish and has become a common female name since the 1970s.[4]
