Q. Is the salaah valid if a person recited the Durood in the second Rakaat of a four Rakaat Fardh Salaah?
A. If a person recited the Durood (Allahumma Salli Ala Muhammad till the end) after reciting Tashahhud (At-Tahiyyatu Lillahi Wassalaawaat till the end) in the first sitting posture (Qadah-e-Ula) of a four Rakaat Fardh Salaah, then it is Waajib (necessary) to make Sajdah-e-Sahw. (Haashiyatut Tahtaawi Al Maraaqil Falaah (1/342)
The method of Sajdah-e-Sahw is to make one Salaam after reciting the Tashahhud in the last sitting posture of Salaah (Qadah-e-Akheerah) after performing two Sajdas. Thereafter, the Tashahhud should be repeated, the Durood should be recited, the Du’aa should read and the Salaat should be completed by making two Salaams.
