A thankful person is thankful under all circumstances. A complaining soul complains even in paradise.

Baháʼu'lláh (1817 CE-1892 CE), Baháʼu'lláh was the founder of the Baháʼí Faith. He was born to an aristocratic family in Persia and was exiled due to his adherence to the messianic Bábí Faith. In 1863, in Iraq, he first announced his claim to a revelation from God and spent the rest of his life in further imprisonment in the Ottoman Empire.
