Sayyiduna Ya'la bin Umayyah (may Allah be pleased with him) says: I said to Sayyiduna Umar bin Khattab (may Allah be pleased with him) that Allah Almighty says: "There is no sin on you if you shorten the prayer if you fear that the disbelievers may harm you" (An-Nisa: 101), and now people are in peace (i.e., is shortening the prayer still permissible or not?). He said: I was also surprised as you are surprised, so I asked the Messenger of Allah (peace and blessings be upon him) about this matter. He (peace and blessings be upon him) said: This is a charity that Allah has given you, so accept His charity (i.e., shorten the prayer during travel even without fear).

`Sayyiduna Ibn Abbas (may Allah be pleased with them both) says that Allah Almighty prescribed through the tongue of your Noble Prophet (peace and blessings be upon him) four rak‘ahs in residence, two in travel, and one rak‘ah in fear.

`Sayyiduna Anas bin Malik (may Allah be pleased with him) says that I offered four rak‘ahs of Zuhr with the Messenger of Allah (peace and blessings of Allah be upon him) in Madinah, and I offered two rak‘ahs of ‘Asr with the Messenger of Allah (peace and blessings of Allah be upon him) at Dhul-Hulaifah.

`Sayyiduna Anas bin Malik (may Allah be pleased with him) says that we set out from Madinah to Makkah with the Messenger of Allah (peace and blessings be upon him), and he continued to perform two rak‘ahs (for each prayer) until he returned. I asked, "How many days did you stay in Makkah?" He said, "Ten days." In another narration, it is mentioned that we set out from Madinah to (Makkah) for Hajj.

Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) performed the prayer of a traveler in Mina, and Sayyiduna Abu Bakr and Umar (may Allah be pleased with them both) also did so, and Sayyiduna Uthman (may Allah be pleased with him) also performed the prayer of a traveler for eight years (or he said: for six years). Hafs (i.e., Ibn Asim) said that Sayyiduna Ibn Umar (may Allah be pleased with them both) would perform two rak‘ahs in Mina and then come to his bedding, so I said: O my uncle! If only you would perform two more rak‘ahs after the obligatory (i.e., the Sunnah)? He replied: If I were to do so, I would complete my obligatory prayer.

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that when the Prophet Muhammad, peace and blessings be upon him, was in a hurry during a journey, he would delay Zuhr until the beginning time of Asr arrived, then combine both. And he would delay Maghrib until when the twilight disappeared, he would combine it with Isha.

`Sayyiduna Ibn Abbas (may Allah be pleased with them both) says that the Messenger of Allah (peace and blessings be upon him) combined the Zuhr and Asr prayers and the Maghrib and Isha prayers in Madinah without fear or rain. In Waki’s narration, it is mentioned that I asked Sayyiduna Ibn Abbas (may Allah be pleased with them both),“Why did the Prophet (peace and blessings be upon him) do this?”He replied,“So that his Ummah would not face hardship.”And in the hadith of Abu Muawiyah, it is mentioned that Sayyiduna Ibn Abbas (may Allah be pleased with them both) was asked,“With what intention did the Prophet (peace and blessings be upon him) do this?”He replied,“He did it with the intention that his Ummah should not face difficulty.”

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that he gave the call to prayer (adhan) for the people on a cold, windy, and rainy night, and at the end of the adhan he said: "Pray in your homes, pray in your homes." Then he said that when the Messenger of Allah (peace and blessings be upon him) was on a journey on a cold and rainy night, he would instruct the mu'adhdhin to announce among the people: "Pray in your tents."

Hafs bin Asim said: I was with Abdullah bin Umar (may Allah be pleased with them) on the way to Makkah, so he led us in two rak'ahs of Zuhr prayer. Then he went on and we went with him until we reached our place of stay and sat down, and we sat with him. Suddenly, his gaze fell upon the place where the prayer had been performed, and he saw some people standing. He asked, "What are they doing?" I said, "They are offering Sunnah prayers." He said, "If I had to offer Sunnah, I would have completed the prayer (i.e., performed the full four rak'ahs of the obligatory prayer)." Then he said, "O nephew! I accompanied the Messenger of Allah (peace and blessings be upon him) during travel, and he never prayed more than two rak'ahs as long as he lived. I also accompanied Abu Bakr (may Allah be pleased with him), and he too never prayed more than two rak'ahs as long as he lived. I also accompanied Umar (may Allah be pleased with him), and he too never prayed more than two rak'ahs as long as he lived. I also accompanied Uthman (may Allah be pleased with him), and he too never prayed more than two rak'ahs as long as he lived. And Allah Almighty has said that in the life of the Messenger of Allah (peace and blessings be upon him) there is a good example for you."

`Sayyiduna Ibn Umar (may Allah be pleased with them) narrates that the Messenger of Allah (peace and blessings be upon him) used to offer voluntary prayers on his mount, regardless of which direction it was facing (it is preferable that at the beginning the mount faces the Qiblah).
