A five-term MLA from the state, Shah's entry into the Upper House will be a boost for the saffron party, which remains in a minority in the Rajya Sabha.
Shah will leave for the state tomorrow and is likely to file his nomination on Friday.
Both the BJP candidates are set for an easy win due to the big majority the party enjoys in the state assembly and there is probability that it may support a candidate for the third seat to make it difficult for the opposition Congress to retain its one seat.
Senior Congress leader Ahmed Patel is currently the MP from the state and his party is likely to renominate him.
The BJP hopes that it can ally with Shankersinh Vaghela, who has left the Congress, to get support from the MLAs loyal to him.
The parliamentary board also named Sampatiya Uikey, a tribal leader from Madhya Pradesh, for the by-poll being held following the death of Anil Madhav Dave.
