Short answer
No. The intention (niyyah) is in the heart, and that is what counts: knowing which prayer you are about to pray as you say Allahu akbar is enough. Later Hanafi scholars said saying it softly is recommended if it helps you focus, but it is not required, and the words never replace the intention in your heart.
Intention is a condition of prayer and its place is the heart: you must know which prayer you are praying, such as the fard of Dhuhr. Saying it with the tongue is not required; later Hanafi scholars considered it mustahabb to help the heart concentrate, while noting that it is not reported from the Prophet ﷺ.
Other madhhabs
- Maliki
- It is better not to say the intention aloud, except for someone troubled by doubts (waswasa).
Explanation
Niyyah means intention. Every act of worship needs it, and for salah it means that when you say the opening Allahu akbar, you know which prayer you are starting. It does not need words, and it does not need to be in Arabic. If someone stopped you and asked "which prayer are you praying?" and you could answer at once, your intention is there.
What to intend in the Hanafi school:
- Fard: name the prayer, such as "the fard of Asr". The number of rakats is not needed.
- Behind an imam: also intend to follow him.
- Sunnah and nafl: a general intention to pray is enough, though naming it is better.
- Qada: see the intention for a qada prayer.
Saying it aloud is not reported from the Prophet ﷺ or the Companions. Later Hanafi scholars, as recorded in al-Durr al-Mukhtar, called saying it softly mustahabb because it helps the heart focus, as long as it is not believed to be required. Some other scholars regard saying it as an innovation. Either way, never say it loudly enough to disturb others, and if you have waswasa (nagging doubts), do not keep repeating it: a single clear intention is enough.

The evidence
Sahih al-Bukhari 1
Sahih... إنما الأعمال بالنيات ...
"Actions are only by intentions."
Intention is required for prayer.
Sunan Abi Dawud 61
Grading to be checked... مفتاح الصلاة الطهور وتحريمها التكبير وتحليلها التسليم ...
"The key to prayer is purification; its start is the takbir and its end is the salam."
The intention is joined to the opening takbir.
Where the ruling is recorded
- al-Durr al-Mukhtar with Radd al-Muhtar, Kitab al-Salah, chapter on the conditions of prayer, the intention. The intention is in the heart; saying it with the tongue is mustahabb in the chosen view.
- Nur al-Idah with Maraqi al-Falah, Chapter on the conditions of prayer. What must be intended for fard, following an imam, and nafl.
