Hazrat Mus'ab bin Sa'd narrates that when Hazrat Sa'd would complete the Tashahhud, he would say these words: I declare Allah to be pure filling the earth and the heavens, and filling whatever is between them, and filling what is beneath the soil. All praise belongs to Allah filling the earth and the heavens, and filling whatever is between them, and filling what is beneath the soil. Allah is the Greatest filling the earth and the heavens, and filling whatever is between them, and filling what is beneath the soil. (Hazrat Shu'bah said: whether Allahu Akbar or Alhamdulillah was said first.) And all praise is for Allah, pure and blessed praise. There is no deity except Allah, He is alone, He has no associate, to Him belongs the dominion and to Him belongs all praise, and He is capable over all things. O Allah, I ask You for all good. After making this supplication, he would say the Salam.
