What should be said after Tayammum?

Question:
Is there a recommended Thikr to be said after Tayammum (dry ablution), just as we do after Wudhoo’ (ablution)?
Answer:
All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
There is no evidence that indicates that there is a certain Thikr to be said after Tayammum. Nevertheless, the Shaafi‘i scholars 
stated that it is recommended to utter the two testimonies of faith. They mentioned that as one of the Sunnah acts of Tayammum. Stating the recommended acts in Tayammum, An-Nawawi 
a Shaafi‘i scholar, said: "The eleventh: it is recommended to follow Tayammum by uttering the two testimonies of faith, just as we mentioned in Wudhoo’ and Ghusl."
Al-Khateeb Ash-Shirbeeni a Shaafi‘i scholar, said: "Uttering the two testimonies of faith means the Thikr that is recommended to be said after Wudhoo’: Ash-hadu anlaa ’ilaaha ’illa Allaah, wahdahu la shareeka lah, wa ash-hadu anna Muhammadan ‘abduhu wa Rasooluh (I bear witness that there is no god worthy or worship but Allaah Alone, there are no partners beside, and that Muhammad is His slave and Messenger). Muslim reported this Hadeeth on the authority of ‘Uqbah ibn ‘Aamir Al-Juhani from the Messenger of Allaah, sallallaahu ‘alayhi wa sallam."
As far as we know, only the Shaafi‘i scholars stated this.
