Reciting durood-e-Ibrahim in the first qa'dah of a fardh salaah
Q: I performed my Zuhr fard salaah. In the qa'dah (sitting) after two rakaats, I recited the tashahhud, durood and the Dua. Then I remembered that it is a four rakaat salaah, and without making salaam, I stood up and continued and completed the Salaah. However, I did not make sajdah-e-sahw. Is my salaah valid?
