Ibn Daylami reported,

I came to Ubayy bin Kaab and said to him, "Something concerning divine decree has troubled my heart. Tell me something, so that perhaps Allah may remove it from my heart."He said, "If Allah were to punish the inhabitants of His heavens and the inhabitants of His earth, He would punish them without being unjust to them. And if He were to show them mercy, His mercy would be better for them than their deeds. If you were to spend the equivalent of Mount Uhud in gold in the path of Allah, Allah would not accept it from you until you believe in divine decree and know that whatever befalls you could not have missed you, and whatever misses you could not have befallen you. If you were to die holding any other belief, you would enter the Fire."Then I went to Abdullah bin Masud, and he said the same. Then I went to Huzaifa bin Yaman, and he said the same. Then I went to Zayd bin Thabit, and he reported the same to me from the Prophet ﷺ.

عن ابن الديلمي قال

أتيت أبي بن كعب فقلت له: وقع في نفسي شيء من القدر، فحدثني بشيء لعل الله أن يذهبه من قلبي، قال: لو أن الله عذب أهل سماواته، وأهل أرضه عذبهم وهو غير ظالم لهم، ولو رحمهم كانت رحمته خيرا لهم من أعمالهم، ولو أنفقت مثل أحد ذهبا في سبيل الله ما قبله الله منك حتى تؤمن بالقدر، وتعلم أن ما أصابك لم يكن ليخطئك، وأن ما أخطأك لم يكن ليصيبك، ولو مت على غير ذلك لدخلت النار. قال: ثم أتيت عبد الله بن مسعود، فقال مثل ذلك، ثم أتيت حذيفة بن اليمان فقال مثل ذلك، قال: ثم أتيت زيد بن ثابت، فحدثني عن النبي ﷺ مثل ذلك.
