What is the explanation and clarification of the Hadith: "that what befell you was not to miss you, and what missed you was not to befall you," which is part of the longer Hadith whose text is: "And if you had gold equal to Mount Uhud and spent it in the path of Allah, He would not accept it from you until you believe in Al-Qadar (Divine Preordainment) and know that what befell you was not to miss you, and what missed you was not to befall you. And indeed, if you die upon other than this, you will enter the Hellfire"?

The summary of the answer is that the aforementioned hadith is narrated by Imam Ahmad, Abu Dawud, and others, from Ibn al-Daylami. It states that belief in Divine Decree (Al-Qadar), both its good and bad, is a condition for the acceptance of deeds and entry into Paradise. The meaning of "What has befallen you was not to miss you, and what has missed you was not to befall you" is that whatever Allah has decreed for you or against you, whether good or evil, will not bypass you, and whatever He has not decreed for you will never afflict you. A similar meaning is found in the hadith of Al-Walid ibn Ubadah ibn al-Samit, emphasizing that belief in Divine Decree is the foundation of the reality of knowledge of Allah, and that the first thing Allah created was the Pen and commanded it to write, so it wrote whatever is to be until the Day of Judgment.
