Abstract
In this paper we show that the only sequences of orthogonal polynomials satisfying \begin{align*} \phi(x)\mathcal{D}_q P_{n}(x)=a_n\mathcal{S}_q P_{n+1}(x) +b_n\mathcal{S}_q P_n(x) +c_n\mathcal{S}_q P_{n-1}(x), \end{align*} () where is a well chosen polynomial of degree at most two, is the Askey-Wilson operator and the averaging operator, are the multiple of Askey-Wilson polynomials, or specific or limiting cases of them.
