Al-Qadar is “the divine will and decree of Allah (swt)”, where He knew, wrote, willed and created all things in due proportion and according to a precise measure. Allah (swt) knew about everything before bringing them to existence and in accordance with proportions and measures which Allah had written in a Book called al-Lawh al-Mahfooz (the Preserved Tablet). Al-Qadaa’ is the perfectly precise execution and accomplishment of all things in accordance with Allah’s Qadar.
The Prophet (ﷺ) defined Iman as: “Faith (الإيمان) has over seventy branches or over sixty branches, the most excellent of which is the declaration that there is no god but Allah, and the humblest of which is the, removal of what is injurious from the path: and modesty is the branch of faith”.
