Abu Bakr al-Aydarus

[2] Abu Bakr spent most of his adult life in Aden, where he was well respected for his societal contributions to the well-being of the city's residents.

[4] In his youth, Abu Bakr studied the teachings of al-Ghazali, and in his early adulthood, he was sent to Aden to undertake missionary duties there.

[5] Nevertheless, he made occasional return trips to his family in Tarim, many of whom relied on a monetary endowment funded by charitable traders in the region.

[6] Abu Bakr was also respected by members of the Adeni Jewish community, providing them refuge when they were harassed by desert bandits.

[8] At least three Arab texts, namely the Tarikh of an-Najm al-Ghazzi, the Jāmiʻ karamāt al-awlīyāʼ of Yūsuf ibn Ismāʻīl Nabhānī and Istifa' al-Safwa li-Tashyat al-Qahwa, mention Abu Bakr's role in the introduction of coffee to the Hadhramawt.

According to the Tarikh of an-Najm al-Ghazzi, Abu Bakr became impressed with the strong stimulating effect derived from eating the berries of a coffee tree during his wanderings.
