"When the prayers were first enjoined they were of two rakʿat each. Later the prayer in a journey was kept as it was but the prayers for non-travelers were completed." Az-Zuhri said, "I asked ʿUrwa what made Aisha pray the full prayers (in journey)." He replied, "She did the same as ʿUthman did."  

قَالَتِ الصَّلاَةُ أَوَّلُ مَا فُرِضَتْ رَكْعَتَيْنِ فَأُقِرَّتْ صَلاَةُ السَّفَرِ وَأُتِمَّتْ صَلاَةُ الْحَضَرِ قَالَ الزُّهْرِيُّ فَقُلْتُ لِعُرْوَةَ مَا بَالُ عَائِشَةَ تُتِمُّ قَالَ تَأَوَّلَتْ مَا تَأَوَّلَ عُثْمَانُ  

The prayer was prescribed as consisting of two rak'ahs, the prayer in travelling remained the same, but the prayer at the place of residence was completed. (Zuhri said he asked 'Urwa why 'A'isha said prayer in the complete form during journey, and he replied that she interpreted the matter herself as 'Uthman did.)  

أَنَّ الصَّلاَةَ أَوَّلَ مَا فُرِضَتْ رَكْعَتَيْنِ فَأُقِرَّتْ صَلاَةُ السَّفَرِ وَأُتِمَّتْ صَلاَةُ الْحَضَرِ قَالَ الزُّهْرِيُّ فَقُلْتُ لِعُرْوَةَ مَا بَالُ عَائِشَةَ تُتِمُّ فِي السَّفَرِ قَالَ إِنَّهَا تَأَوَّلَتْ كَمَا تَأَوَّلَ عُثْمَانُ  

"The Salah was enjoined two Rak'ahs at a time, then the Salah when traveling remained like that, but the Salah while resident was increased."  

فُرِضَتِ الصَّلاَةُ رَكْعَتَيْنِ رَكْعَتَيْنِ فَأُقِرَّتْ صَلاَةُ السَّفَرِ وَزِيدَ فِي صَلاَةِ الْحَضَرِ  

The prayer was prescribed as consisting of two rak'ahs both when one was resident and when travelling. The prayer while travelling was left according to the original prescription and the prayer of one who was resident was enhanced.  

فُرِضَتِ الصَّلاَةُ رَكْعَتَيْنِ رَكْعَتَيْنِ فِي الْحَضَرِ وَالسَّفَرِ فَأُقِرَّتْ صَلاَةُ السَّفَرِ وَزِيدَ فِي صَلاَةِ الْحَضَرِ  

[Machine] The prayer was prescribed as two units, but the Messenger of Allah ﷺ added in the prayer of noon and left the prayer of travel as it is.  

فُرِضَتِ الصَّلَاةُ رَكْعَتَيْنِ فَزَادَ رَسُولُ اللهِ ﷺ فِي صَلَاةِ الْحَضَرِ وَتَرَكَ صَلَاةَ السَّفَرِ عَلَى نَحْوِهَا  

[Machine] "The prayer was initially ordained with two units (rak'ahs). Then the prayer of travel (safar) was established with a shortened form, while the prayer of residence (hadar) was performed in its complete form." So I asked, "What was the reason for completing the prayer during travel?" He (Uthman) said, "It was interpreted (or understood) in this way as Uthman had also interpreted it."  

«إِنَّ الصَّلَاةَ أَوَّلَ مَا فُرِضَتْ رَكْعَتَيْنِ فَأُقِرَّتْ صَلَاةُ السَّفَرِ وَأُتِمَّتْ صَلَاةُ الْحَضَرِ» فَقُلْتُ مَا لَهَا كَانَتْ تُتِمُّ الصَّلَاةَ فِي السَّفَرِ؟ قَالَ إِنَّهَا تَأَوَّلَتْ كَمَا تَأَوَّلَ عُثْمَانُ  

The prayer was prescribed as consisting of two rak'ahs both when one was resident and when travelling. The prayer while travelling was left according to the original prescription and the prayer of one who was resident was enhanced. (Using translation from Abū Dāʾūd 1198)  

أَنَّهَا قَالَتْ «فُرِضَتِ الصَّلَاةُ رَكْعَتَيْنِ رَكْعَتَيْنِ فِي الْحَضَرِ وَالسَّفَرِ فَأُقِرَّتْ صَلَاةُ السَّفَرِ وَزِيدَ فِي الْحَضَرِ»  

[Machine] She said, "The first thing that was obligated regarding prayer, whether in settled or traveling situations, is two units of prayer. Then the prayer was increased in settled situations, while it was simplified in traveling situations."  

أَنَّهَا قَالَتْ «أَوَّلُ مَا فُرِضَتِ الصَّلَاةُ فِي الْحَضَرِ وَالسَّفَرِ رَكْعَتَيْنِ ثُمَّ زِيدَ فِي صَلَاةِ الْحَضَرِ وَأُقِرَّتْ فِي السَّفَرِ»  

"The Salah was enjoined two Rak'ahs at a time, then the Salah when traveling remained like that, but the Salah while resident was increased." (Using translation from Nasāʾī 455)  

«فُرِضَتِ الصَّلَاةُ رَكْعَتَيْنِ فَأُقِرَّتْ صَلَاةُ السَّفَرِ وَزِيدَ فِي صَلَاةِ الْحَضَرِ»  

"عَنْ عَائِشَةَ قَالَتْ: فَرَضَ اللهُ - تَعَالَى- آيَةَ الصَّلَاةِ أَوَّلَ مَا فَرَضَهَا رَكْعَتَيْنِ ثُمَ أَتَمَّهَا لِلْحَاضِرِ، وَأُقِرَّتْ صَلَاةُ السَّفَرِ عَلَى الفَرِيضَةِ الأُولَى".
