Q: If My child takes the Sajda (things on which we do prostration or the Sujoud) away while I was praying. What do I do?
A: If there is enough time, you should stop your prayer and get what is lawful to do Sujoud on (and perform it again). If not, you should do Sujoud on what is available such the carpet or the clothes, but not on the hands or fingers.
