After completing his Abitur, Hübsch refused military service and during the German student movement of the APO, he was affiliated with, inter alia, the Kommune 1.

He was also the co-founder of the leftist organisation Club Voltaire in Frankfurt [4] and opened the first alternative bookstore in Germany, the "Heidi Loves You" shop in Frankfurt-Bockenheim.

Some years later, after a meeting with Mirza Nasir Ahmad, the third Ahmadi Caliph, back in Germany, he joined the Ahmadiyya movement, took on the name Hadayatullah (Guided by Allah) and dedicated himself to the study of Islam, being associated with the Noor Mosque in Frankfurt, where he would later serve as Imam himself and deliver the Friday sermons in German.

[7] His work featured regularly for eight years in the Frankfurter Allgemeine Zeitung which also published his poems until 1979, although after he embraced Islam, he had received a notice of termination which stated that Hübsch was "an extraordinary phenomenon that bustled every bourgeois frame of the West".

He also translated several books from English into German, including Jesus in India and the classical Islamic work Tazkirat al-Awliya by Attar of Nishapur.

His attempts to foster an understanding of migrants and Islam among the New Right partially received strong criticism by those on the left who thought his engagement with the movement was inappropriate.
