Translation:

69. On their account no responsibility falls on the righteous but (their duty) is to remind them that they may (learn to) fear Allah.

Notes (Tafseer)

892. "Evil to him who evil thinks," or evil does. Every man is responsible for his own conduct. But the righteous have two duties: (1) to protect themselves from infection, and (2) to proclaim God's truth, for even in the most unlikely circumstances, it is possible that it may have some effect.
