Ma'bad al-Juhani
Ma'bad ibn Kalid al-Juhani معبد الجهني, was from the tribe of Juhainah which lived and still live in around the city of Medinah in Saudi Arabia. He was Qadari, an idea he got from Sinbuya, and was declared as misguided by some of the companions of the Islamic prophet Muhammad. He was crucified by the orders of the Caliph Abd al-Malik in Damascus. He was the first man, after Sinbuya, who discussed the Qadr. His ideas was later followed by Abū Marwān Gaylān ibn Mūslīm ad-Dimashqī an-Nabati al-Qībtī.
