Wisdom behind secret and loud recitation

Q 5: Why are Zhuhr (Noon) and `Asr (Afternoon) Prayers offered as Sirri Salahs (Prayer with subvocal recitation) while Maghrib (Sunset) and `Isha' (Night) Prayers are Jahri Salahs (Prayer recited aloud)?

A: We do this following the example of the Prophet (peace be upon him). We offer Sirri Salah in the Salahs he recited inaudibly, and we offer Jahri Salah (Part No. 6; Page No. 417) in the Salahs he recited aloud, as Allah stated, Indeed in the Messenger of Allâh (Muhammad صلى الله عليه وسلم) you have a good example to follow (Surah Al-Ahzab, 33: 21). The Prophet (peace be upon him) stated, Offer Salah in the manner you have seen me doing. Narrated by Al-Bukahri in his Sahih (authentic) Book of Hadith. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
