1. If a person reads the ruku tasbeeh in sajda and due to the mistake he makes a sajda sahwa, is the salah valid?
2. How many sajda tasbeehs can a person read in tahjjud salaah?
1. He did not need to make sajda-e-sahw. However the Salaah is valid.
2. Any amount he wishes.
And Allah Ta’ala (الله تعالى) knows best.
