The Zuhr prayer (Arabic: صَلَاة ٱلظُّهْر, Ṣalāt aẓ-Ẓuhr; IPA: [sˤa.laːt aðˤ.ðˤuhr], "noon prayer"), also transliterated Dhuhr, Duhr or Thuhr, is the second of the five daily obligatory prayers (salah) for practicing Muslims. It contains four units (rakaʿāt) and begins after the Sun reaches its zenith.On Friday, the Zuhr prayer is replaced or preceded by Friday prayer, which is obligatory for Muslim men who are above the age of puberty and meet certain requirements to pray in congregation either in a mosque or with a group of Muslims.
As you travel every day for work, you must perform you Salah as full in both places, your home and your work place. Every one who travels for work three days a week or more, his Salah is full.
It is compulsory to pray Fajr prayers and every prayer within it’s
time before it lapses (i.e. becomes Qadha). The Mo’min must do
everything that he can to perform all his prayers within its time.
You need to change your sleeping timing to be sure that you can wake up
to perform the Fajr prayer. The Hadith says : He who sleeps during the
time of Fajr prayer and misses the prayer will be called from the sky
: O loser !
If for any reason like illness etc. You could not wake up for Fajr,
then you must perform it as Qadha on the same day or better as soon as
you wake but that can never be usual procedure. You need to set an
alarm or request your family members to wake you up or your friends to
phone you to be sure that you wake up for Fajr prayers on time.
According to authentic Hadeeths, the loss of a person missing Fajr
prayer is more than all the treasures of this world.
Thank you for your question. According to the school of Ahl al-Bayt (as), there is no problem with praying your intended prayer in congregation in either scenario.
May you always be successful.
In such cases when there is not enough time to recite the full Nafilah of Zoh or Asr, you can pray just 4 or even 2 Rak'ats as Nafilah for each Zohr and Asr. If you could not find time , then you can recite the Nafilah later on as Qadha.
Reciting Quran in Zuhr and Asr Prayers must be with Ekhfaat which means with low voice which can be heard by you in usual cases. It is like whispering with out clear voice. Just moving the lips with out hearing anything is not enough in Ekhfaat.
Every Sunnah (Recommended) Prayer is in two Rak'ats and not more. The Sunnah prayer for Zohr is in fact Rak'ats (2+2+2+2). This is according to the Prophetic Sunnah narrated from Ahlul Bayt (AS), although some Muslim sects pray 4 Rak'ats only according to their own sect.
