Which of the following prayers has a complete silent recitation?

The prayer that has a complete silent recitation is Zuhr. In Zuhr prayer, the first two Rak'ahs (units of prayer) are performed with audible recitation of Surah Al-Fatiha and another Surah from the Quran, while the last two Rak'ahs are performed with a complete silent recitation. During the silent recitation, the recitation of Surah Al-Fatiha and another Surah are recited softly, in a way that only the person praying can hear themselves. This is in contrast to the audible recitation of the first two Rak'ahs, where the recitation is performed in a louder voice. The reason for the complete silent recitation in the last two Rak'ahs of Zuhr prayer is to emphasize the importance of being mindful and focused in prayer, even in a silent state. This is a reminder to the person praying that the prayer is a conversation between them and Allah, and they should strive to maintain concentration and devotion throughout the prayer.
