Diferent parts of Quran in one rakah

[munir rana]

Dear All

Salam.

From a response of Joseph Islam (to Wazir) I came to know that it would be nice to avoid uttering `Qul' before reciting suras like Ikhlas in ritual prayer. Very Logical.
My question : Is there any problem if i recite diferent parts/verses of Quran (which all are prayer) in one rakah.

Thanks.

Salam.
