Islamic Laws : Wudhu » Introduction
Fatawa of Ayatullah al Uzama Syed Ali al-Husaini Seestani
254. While performing Wudhu, it is obligatory to wash the face and the hands once, and it is recommended to wash them twice.
Washing them three or more times is haraam. As regards to which washing should be treated as the first, it will depend upon washing the face and hand thoroughly, leaving no room for precaution, with the niyyat of Wudhu.
So, if he pours water on his face ten times with the intention of the first washing, there is no harm, but when he will then wash with the niyyat of Wudhu, it will be called the first time. Thus, he can go on pouring water on his face several times, and in the final wash, make the niyyat of Wudhu. But if he follows this procedure, then the face and the hands should be washed once only, as an obligatory precaution.
