Q: I have a wooden flooring and I found out after it has been placed that those who placed it used a wood glue which could contain najais substances. Actually, I read the notice on the box but not the full list of components was given, instead it wrote ‘…and other selected chemicals.’ I am not sure if it contains alcohol or something. Can I pray Salah on it?
A: If you are not certain that impure substance were used then regard it as paak.
And Allah Ta’ala (الله تعالى) knows best.
ولو أيقن بالطهارة وشك بالحدث أو بالعكس أخذ باليقين ولو تيقنهما وشك في السابق فهو متطهر (الدر المختار 1/150)
