The ruling on praying on the house rugs in the presence of young children

Question:
His last question says that he has young brothers, and when he prays in the house, he is troubled by doubts for fear that the place where he prayed is not pure. What is your guidance, Your Eminence the Shaykh, and how should he act? May Allah reward you with good.

Answer:
The default is that the earth is pure, and the default is that the rugs are pure; this is the default. So there is no prohibition on praying on the earth or the rug unless you know with certainty that ritual impurity has affected it. Otherwise, the default is purity, even if you have doubts, and even if you have young children. The default is purity for the earth and the rug. There is no blame on you for praying a voluntary prayer on this rug or on this earth. As for the obligatory prayer, you must pray with the people in the mosques, praying in congregation with the people. However, if you set up a prayer area, that would be better. You can set up a known prayer area in part of your house where you pray your voluntary prayers, or you can have a special mat that you pray on and keep for yourself when you pray your tahajjud or voluntary prayers, so that your heart is reassured that your prayer area is pure. Otherwise, the default is purity, and praise be to Allah. May Allah reward you with good.
