Hadith record

Hadith.730 - Imam Jafar ibn Muhammad Al-Sadiq (as) was asked about praying in the houses of the Magians (Zoroastrians) if they are sprinkled with water, and He said: "There is no harm in it." He then mentioned that he sometimes saw someone on the road to Makkah sprinkling water on the spot where they placed their forehead before prostrating, while at other times, they did not sprinkle water if they deemed the place to be clean.
