The ruling on combining two surahs in a single rak'ah

Question:
The questioner says: Is it permissible to combine two surahs in the obligatory prayer in a single rak'ah?

Answer:
There is nothing wrong with that. Allah the Exalted said: So one recites whatever is easy for him, whether it is a surah or surahs, a verse or verses. Praise be to Allah; the matter is broad in this regard, and the more one recites, the better it is, unless it becomes difficult for the ma'mum (those praying behind the imam) behind him. Yes.
