Born Hâşimîzâde Abdullah Efendi in 1670 in Istanbul, his father was Sayyid Hassan al-Hashimite, the imam of Imrahor Mosque.[1] He was born into a family of calligraphers and grew up in the 'Yedikuleli' district from which he derived the nickname. He was descended from the prophet, Mohammed through both his paternal and maternal line, which allowed him to use the title of Seyyid. He studied calligraphy with the great master, Hâfiz Osman.[2]
At one point Ahmed III was so intrigued by the ink that Seyyid used in his calligraphy, that he sent a messenger to learn the secret. Seyyid sent back a full inkwell with the messenger. When the Sultan received the gift, he reportedly emptied the ink, refilled the inkwell with gold, and sent it back.[4]
