In his section praising Abu Bakr in Manteq al-Tayr, Farid al-Din Attar highlights several core Sufi themes. First, he invokes the motif of profound companionship by referencing the Quranic phrase 'thani athnayn' (the second of the two), denoting Abu Bakr's presence with the Prophet in the Cave of Thawr. Attar then portrays him as the ultimate receptacle for divine secrets ('Siddiq'), illustrating a direct, intimate transmission of spiritual knowledge from the Prophet's heart to his. Finally, Attar emphasizes the virtue of rigorous spiritual restraint and ascetic silence, depicted through the historical imagery of Abu Bakr keeping a stone in his mouth to prevent idle or untimely speech.
