The magnitude of the reward is proportionate

السلام عليكم

بِسْمِ اللهِ الرَّحْمنِ الرَّحِيمِ

Verily, the magnitude of the reward is proportionate to the magnitude of the affliction. And indeed when Allah loves people He afflicts them, and those who accept it gladly receive Allah's pleasure, but those who are displeased receive Allah's displeasure.

[Tirmidhi, Ibn'majah]
