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.
