Is it valid to pray the Duha prayer as four Rak'ahs with one Tasleema and two Tashahhuds?

It is permissible to pray four cycles (rak'ats) of Duha prayer with two tashahhuds and one salutation (taslima), just as it is permissible to perform voluntary prayers of four rak'ats with two tashahhuds and one salutation. There are texts that permit this, including the hadith of Aisha: "He (the Prophet) used to pray four rak'ats for Duha, without separating them with a salutation." It is also permissible to perform eight rak'ats with one salutation, and it is permissible to limit oneself to one tashahhud at the end, or a tashahhud after every two or four rak'ats.
