Yahya b. Umayya said:

I told 'Umar b. al-Khattab that Allah had said:" You may shorten the prayer only if you fear that those who are unbelievers may afflict you" (Qur'an, iv. 101), whereas the people are now safe. He replied: I wondered about it in the same way as you wonder about it, so I asked the Messenger of Allah (ﷺ) about it and he said: It is an act of charity which Allah has done to you, so accept His charity.

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ وَزُهَيْرُ بْنُ حَرْبٍ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ قَالَ إِسْحَاقُ أَخْبَرَنَا وَقَالَ الآخَرُونَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ، عَنِ ابْنِ جُرَيْجٍ، عَنِ ابْنِ أَبِي عَمَّارٍ، عَنْ عَبْدِ اللَّهِ بْنِ بَابَيْهِ، عَنْ يَعْلَى بْنِ أُمَيَّةَ، قَالَ قُلْتُ لِعُمَرَ بْنِ الْخَطَّابِ ‏{‏ لَيْسَ عَلَيْكُمْ جُنَاحٌ أَنْ تَقْصُرُوا، مِنَ الصَّلاَةِ إِنْ خِفْتُمْ أَنْ يَفْتِنَكُمُ الَّذِينَ كَفَرُوا‏}‏ فَقَدْ أَمِنَ النَّاسُ فَقَالَ عَجِبْتُ مِمَّا عَجِبْتَ مِنْهُ فَسَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْ ذَلِكَ ‏.‏ فَقَالَ ‏

‏ صَدَقَةٌ تَصَدَّقَ اللَّهُ بِهَا عَلَيْكُمْ فَاقْبَلُوا صَدَقَتَهُ ‏

Travel is a piece of torment, and it is most likely to involve tiredness and hardship. Hence, Allah Almighty alleviates things for travelers and facilitates the Shar‘i rulings for them, especially those related to prayer and fasting. In this Hadīth, Ya‘la ibn Umayyah (may Allah be pleased with him) relates that he asked ‘Umar ibn al-Khattāb (may Allah be pleased with him) about the verse that reads: {When you are traveling through the land, there is no blame on you to shorten the prayer, if you fear that the disbelievers may harm you.} [Surat an-Nisā’: 101] It means: If you travel in the land, there is no sin on you in shortening the four-Rak‘ah prayers (the Zhuhr, ‘Asr, and ‘Ishā’ prayers) to two Rak‘ahs - if you fear harm from the disbelievers. "And people have become secure" now, and their fear, which was the reason behind prescribing the shortening of prayer, is no longer there. So, why do they shorten the prayer? Or what is the objective of shortening if its reason is no longer there? In response, ‘Umar (may Allah be pleased with him) informed him that he had the same thought as Ya‘la ibn Umayyah and so he asked the Messenger of Allah (may Allah's peace and blessings be upon him) about shortening the prayer in the absence of its reason - namely the fear from the enemy - and the existence of security, and the Prophet (may Allah's peace and blessings be upon him) told him that shortening the prayer is a favor from Allah Almighty which He bestowed upon the Muslim Ummah and honored them with; it is a charity Allah has given them, by way of facilitation and mercy. "So, accept His charity," i.e., whether there is fear or not; shortening the prayer is established in case of security as well. Allah's words: That the disbelievers may harm you} refers to what is most likely, for most of the journeys of the Prophet (may Allah's peace and blessings be upon him) and his Companions were not fear-free, given the multitude of fighting enemies at the time. This indicates that the shortening of prayer during travel was prescribed to make things lenient and easy for people, and it does not have the sense of order or obligation for the traveler. Indeed, the Ummah unanimously agreed that a person to whom charity is offered is not obligated to accept it. In the Hadīth: Shortening the prayer during travel with or without fear And in it: Demonstrating the mercy of Allah Almighty and His complete favor upon His servants, as He prescribed for Muslims to shorten the prayer during travel given the hardship they suffer..
