Surah 6. Al-An'am, Ayah 69

This is a paraphrase of the elliptic expression wa-lakin dhikra ("however, an admonition").

"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.
