Nahj al-Balāgha

۳۸۸. وَقَالَ (عليه ‏السلام): أَلَا وإِنَّ مِنَ الْبَلاَءِ الْفَاقَةَ وَأَشَدُّ مِنَ الْفَاقَةِ مَرَضُ الْبَدَنِ، وَأشدُّ مِنْ مَرَضِ الْبَدَنِ مَرَضُ الْقَلْبِ.

388. Amīr al-mu’minīn, peace be upon him, said: Beware that destitution is a calamity, but worse than destitution is ailment of the body, while worse than bodily ailment is the disease of the heart.

أَلَا وإِنَّ مِنَ النِّعَم سَعَةَ الْمَالِ، وَأَفْضَلُ مِن سَعَةِ الْمَالِ صِحّةُ الْبَدَنِ، وَأَفْضَلُ مِنْ صِحَّةِ الْبَدَنِ تَقْوَى الْقَلْبِ.

Beware that plenty of wealth is a blessing, but better than plenty of wealth is the health of the body, while still better than the health of the body is the chastity of heart.
