It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "What I fear most for my Ummah in its last age is: seeking to know one's fortune through the stars, denying the divine decree (qadar), and the injustice of the ruler."
