Niyyah does not need to be spoken. It is an intention made in the heart. Before any act of worship, a Muslim should intend sincerely to do it for the sake of Allah.
What is Niyyah in prayer?
Niyyah (النِّيَّةُ) is the intention of the heart to perform a specific act of worship for Allah alone. In Salah, it means to firmly resolve — before the opening takbir — which prayer you are about to offer (for example, the Fard of Fajr, 2 rak'ahs) and that you are doing it purely for Allah's sake.
Why is it important?
The Prophet ﷺ said: “Actions are but by intentions, and every person will have only what he intended.” (Bukhari & Muslim). Without niyyah, an act of worship is not valid — it is what turns a movement into an accepted prayer, and what earns the reward from Allah.
Does it need to be said aloud?
No. The niyyah lives in the heart — that is where it must be present, and Allah knows what is in the hearts. Saying it on the tongue is not a requirement in any of the four schools; some scholars consider it a helpful aid to focus, others discourage speaking it. What is essential is that the heart is clear about which prayer is being offered, for the sake of Allah.
