Hadith: If you spend the like of Uhud in gold, Allah will not accept it from you until you believe in predestination, and know that what has befallen you would not have missed you and what has missed you would not have befallen you. If you die on other than this, you will be among the people of Hellfire

عن ابن الدَّيْلَمِي قال: أتيتُ أُبَيَّ بن كعب فقلتُ: في نفْسي شيء من القدر، فحَدِّثْني بشيء لعل الله يُذْهِبَه مِن قلبي. فقال: «لو أنفقتَ مثل أُحُد ذَهَبًا ما قَبِلَه الله منك حتى تؤمن بالقدَر، وتعلمَ أنَّ ما أصابك لم يكن ليُخطِئك، وما أخْطأك لم يكن لِيُصِيبَك، ولو مُتَّ على غير هذا لكنتَ مِن أهل النار». قال: فأتيتُ عبد الله بن مسعود، وحذيفة بن اليمان، وزيد بن ثابت، فكلهم حدَّثني بمثل ذلك عن النبي صلى الله عليه وسلم .
[صحيح] - [رواه أبو داود وابن ماجه وأحمد]

Ibn Ad-Daylami reported: 'I went to Ubayy ibn Ka‘b and said: "There is something in my heart about predestination, so tell me something in the hope that Allah will remove it from my heart." He said: "If you spend the like of Uhud in gold, Allah will not accept it from you until you believe in predestination, and know that what has befallen you would not have missed you and what has missed you would not have befallen you. If you die on other than this, you will be among the people of Hellfire." He added: "Then, I went to ‘Abdullāh ibn Mas‘ūd, Hudhayfah ibn al-Yamān, and Zayd ibn Thābit, and each of them told me the same thing on the authority of the Prophet (may Allah's peace and blessings be upon him).''

Explanation

‘Abdullāh ibn Fayrūz Ad-Daylami (may Allah have mercy upon him) said that he had some doubts about predestination and feared that he would end up denying it. Therefore, he asked some scholars from among the Companions of the Prophet (may Allah's peace and blessings be upon him) about it in order to solve this problem. This shows that a believer ought to ask scholars about things that are confusing him, as Allah, the Almighty, says: {So ask the people of the message [i.e., former scriptures] if you do not know} [Sūrat An-Nahl: 43]. All the scholars told him that he must believe in the Divine Decree and predestination. They also told him that spending a great amount of wealth would not be accepted from anyone who does not believe in predestination, and that anyone who dies without believing in it will be one of the denizens of the Hellfire.
