الاعتِبارُ مُنذِرٌ ناصِحٌ، مَن تَفَكَّرَ اعتَبَرَ، ومَنِ اعتَبَرَ اعتَزَلَ، ومَنِ اعتَزَلَ سَلِمَ.

The moral lesson is a sincere warner. Whoever contemplates takes lesson, and whoever takes the lesson on board keeps away from making the same mistake twice, and whoever keeps away remains safe.

Bihar al-Anwar, v. 78, p. 92, no. 101
