The example of obedience that grows and increases, is like a seed that you plant, which becomes a tree, then bears fruit, and you ate this fruit and planted their seeds again and whenever the tree bears fruit you eat it and plant its seeds.  The exact example can be applied to sins and the way they increase.

There is an old proverb and the wise will understand it: ‘The reward for good deeds is that they are followed by other good deeds, and the punishment for bad deeds is that they are followed by other bad deeds.’

—Ibn al-Qayyim
