Praying while traveling (qasr)

Praying while traveling (qasr). Qasr (shortening of prayer) is the form of shalat that a traveller performs while on a lawful journey. The traveller has been enjoined to shorten all the obligatory prayers that have four (4) Raka'ats to two (2) Raka'ats.

These prayers are Zuhr, Asr and isha'i excluding Subhi and Maghreb prayers. (any traveling that is above 3 miles to nine miles Qasr is mandatory upon the traveller) The Sunnah of solaat while traveling is that, as long as you will return home then you should pray taqseer (shorten your solaat). 

 if you travel to any place for business or visit or treatment, you can pray qasr (shorten your solaat). for as long as you stay there. when you travel to Hajj, you pray qasr (shorten your solaat). until you return home when on a business trip to any place you can pray qasr throughout your stay... 

And there is no harm if you complete your solaat after three days of arrival. Or when ever you wish. 

Allaah (Swt) says in the Glorious Quran:

"And when you (Muslims) travel in the land, there is no sin on you if you shorten your Solaat (prayer) if you fear that the disbelievers may attack you, verily, the disbelievers are ever unto you open enemies." [Al-Quran- Suratun Nissa :101]

Narrated by Abdullah ibn Umar (may Allaah be pleased with him) that "I have travelled in the companion of the Messenger of Allaah (peace and blessings be be upon him) Abubakar, Umar and uthman (may Allaah be pleased with them) and I have never seen anyone of them exceed 2 raka'ars in (4 raka'ats prayers) while on a journey (Sahih ukhari & Muslim)

Narrated by Abu Ya'ala (may Allaah be pleased with him) that '' I once asked Umar Ibn Khatab (may Allaah have mercy on him) "why are you still doing Qasri after all we are now safe from the attack of unbelievers ? Umar (RA) replied.

"I had also asked the Messenger of Allaah (peace and blessings be upon him) the same question , and he told me that (Qasr) is a gift (of special favour) from Allaah to us, so let us just accept His gift. (Sahih Muslim)

Narrated by Ibn Abbas (may Allaah be pleased with him) that the Messenger of Allaah (peace and blessings be upon him) once stayed for nineteen days and prayed (Qäsr) shortened prayers. So when we travel led (and stayed) for nineteen days, we used to shorten the prayer but if we travelled (and stayed) for a longer period we used to offer the full prayer. [Sahih Bukhari]

Narrated by Yahya bin Ishaq (may Allaah be pleased wirh him) I heard Anas saying, "We travelled with the Messenger of Allaah (peace and blessings be upon him) from Medina to Mecca and offered two Rakat (for every prayer) till we returned to Medina." I said, "Did you stay for a while in Mecca?" He replied, "We stayed in Mecca for ten days." (Sahih Bukhari)

Narrated by Anas Ibn Malik (may Allaah be pleased with him) that “when the Messenger of Allaah (peace and blessings be upon him) went out on a journey of three miles or three Farasikh, he used to pray two Raka’at,” [Sahih Muslim)
