Muslimpress:There are five different times for prayers in Islam(Morning, Noon, Evening, Night, and Midnight). The point about the prayers is that some of them are supposed to be recited out loud and others silently.Here is why:Firstly:The Muslim is required to follow the Prophet(PBUH) and follow his example, whether he knows the reason behind a ruling or he does not. Allah says(interpretation of the meaning): “Indeed in the Messenger of Allah(Muhammad) you have a good example to follow for him who hopes for(the Meeting with) Allah and the Last Day, and remembers Allah much”[al - Ahzaab 33:21] He should also be certain that Islam is based on great wisdom, but this wisdom may be known to us or we may be unaware of it, or we may know some of it and not the rest of it.Secondly: Some of the scholars have pondered the reason why Quran is recited out loud in the nighttime prayers and silently in the daytime prayers, and the summary of what they have mentioned concerning that is: “The night is a time when people are quiet, alone and more focused, so it is prescribed to recite Quran out loud at that time so as to make manifest the pleasure of a person’s conversing with his Lord, and so that the heart, tongue and ears will be involved in the recitation.” This meaning is suggested by the verse in which Allah says (interpretation of the meaning): “Verily, the rising by night (for Tahajjud prayer) is very hard and most potent and good for governing oneself, and most suitable for (understanding) the Word (of Allah). “Verily, there is for you by day prolonged occupation with ordinary duties” [al-Muzzammil 74:6-7]   Ibn Katheer said: The point is that this rising may be at any time of night. What is meant here is that when praying at night, both the heart and the tongue are focused on the recitation, hence Allah says (interpretation of the meaning): “Is very hard and most potent and good for governing oneself, and most suitable for (understanding) the Word (of Allah)” i.e., the mind will be more focused when reciting and will understand the words more than during the day, which is a time when people move about and there is a great deal of noise, and it is the time of seeking provision.   Al-Qurtubi (19/40) said: What is meant is that the heart, sight, hearing and tongue work together in harmony when reciting Quran, because voices and movements are stilled.   It says in Tuhfat al-Muhtaaj: There remains the wisdom behind reciting out loud – what is it? It may be that it is because night is the time when one is alone and people get together for lighthearted talk. So it is prescribed to recite Quran out loud at that time so as to make manifest the pleasure of a person’s conversing with his Lord. This applies only to the first two rak’ahs, because the worshipper has more energy then. Because the day is the time of distractions and mixing with people, it is required to recite silently, because the daytime is not the best time to focus fully on conversing with Allah. The morning (Fajr) prayer is joined to the night prayers because its time is not usually a time when there are distractions, like Friday.
