Imam Ja‘far al-Ṣadiq (as): There are five things which if one where to lose just one of them it would render his life incomplete, his intellect short-lived, and his heart preoccupied. The first of these is health of the body; the second is security; the third is ample sustenance; the fourth is a compatible companion.

And the fifth one, which sums up these four things, is tranquility. Sheikh Ṣadūq, al-Khiṣāl
