Ibn ‘Umar had a friend from the people of Syria who used to correspond with him. ‘Abd Allah b. ‘Umar wrote to him: I have been informed that you have talked something about Divine decree. You should write it to me, for I heard the Messenger of Allah ﷺ say: Among my community there will be people who will falsify Divine decree. (Using translation from Abū Dāʾūd 4613)
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّهُ سَيَكُونُ فِي أُمَّتِي أَقْوَامٌ يُكَذِّبُونَ بِالْقَدَرِ
