(The above interpretation is based on my own prosification, which goes as follows: अयम् दुर्मतिः शिवादीन् देवान् साधयताम् आगमानाम् किमपि प्रामाण्यम् अभीः आक्षिपति, शिशौ पुत्रे (तु) विकृतिम् ईषत् अवेक्ष्य भीतः प्रतिनिशम् सबलिः श्मशानम् धावति| I am not sure about the placement of किमपि.)
Source: Suktimuktaavali (13th century) Chapter 89 Verse 16. The compiler seems to indicate that the above couplet was authored by the same poet who wrote this verse.
Notes: In various treatises, including proto-medical (ayurvedic) compendia such as those by Sushruta, many diseases are attributed to 'malignant spirits', frequently called grahas (ग्रह) or "possessors", and propitiatory rituals for these spirits, involving the sacrifice of edibles and other items and often performed at locations such as crematoria or crossroads at night, are prescribed as 'treatments'.
This snippet might be a jab at nontheistic traditions that still maintain a belief in supernatural forces and ritualism, or just at an argumentative hypocrite who is only an "atheist until the airplane starts falling."
