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)?
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.
