فَاعْلَمْ أَنَّ كُلَّ عَمَل نَبَاتٌ، وَكُلَّ نَبَات لاَ غِنَى بِهِ عَنِ الْمَاءِ، وَالْمِيَاهُ مُخْتَلِفَةٌ، فَمَا طَابَ سَقْيُهُ طَابَ غَرْسُهُ وَحَلَتْ ثَمَرَتُهُ، وَمَا خَبُثَ سَقْيُهُ خَبُثَ غَرْسُهُ وَأَمَرَّتْ ثَمَرَتُهُ.
You should also know that every action is like a vegetation, and a vegetation cannot do without water while waters are different. So where the water is good the plant is good and its fruits are sweet, whereas where the water is bad, the plant will also be bad and its fruits will be bitter.
