"The prayer of the resident was enjoined on the tongue of your Prophet ﷺ, four (rak'ahs), and the prayer of the traveler is two rak'ahs, and the prayer of fear is one rak'ah." (Using translation from Nasāʾī 1441)
«فُرِضَتْ صَلَاةُ الْحَضَرِ عَلَى لِسَانِ نَبِيِّكُمْ ﷺ أَرْبَعًا وَصَلَاةُ السَّفَرِ رَكْعَتَيْنِ وَصَلَاةُ الْخَوْفِ رَكْعَةً»
Originally, two rakʿat were prescribed in every prayer. When the Prophet ﷺ migrated (to Medina) four rakʿat were enjoined, while the journey prayer remained unchanged(i.e. two rakʿat).
فُرِضَتِ الصَّلاَةُ رَكْعَتَيْنِ ثُمَّ هَاجَرَ النَّبِيُّ ﷺ فَفُرِضَتْ أَرْبَعًا وَتُرِكَتْ صَلاَةُ السَّفَرِ عَلَى الأُولَى
Allah has prescribed the prayer through the word of your Prophet ﷺ as four rak'ahs when resident, two when travelling, and one when danger is present.
فَرَضَ اللَّهُ الصَّلاَةَ عَلَى لِسَانِ نَبِيِّكُمْ ﷺ فِي الْحَضَرِ أَرْبَعًا وَفِي السَّفَرِ رَكْعَتَيْنِ وَفِي الْخَوْفِ رَكْعَةً
"The prayer of the resident was enjoined on the tongue of your Prophet ﷺ, four (rak'ahs), and the prayer of the traveler is two rak'ahs, and the prayer of fear is one rak'ah."
فُرِضَتْ صَلاَةُ الْحَضَرِ عَلَى لِسَانِ نَبِيِّكُمْ ﷺ أَرْبَعًا وَصَلاَةُ السَّفَرِ رَكْعَتَيْنِ وَصَلاَةُ الْخَوْفِ رَكْعَةً
"Allah, the Mighty and Sublime, enjoined the prayer on the tongue of your Prophet ﷺ: While a resident four (rak'ahs), while traveling two, and at times of fear one."
إِنَّ اللَّهَ ﷻ فَرَضَ الصَّلاَةَ عَلَى لِسَانِ نَبِيِّكُمْ ﷺ فِي الْحَضَرِ أَرْبَعًا وَفِي السَّفَرِ رَكْعَتَيْنِ وَفِي الْخَوْفِ رَكْعَةً
"Allah (SWT) enjoined the prayer on the tongue of your Prophet ﷺ: four (rak'ahs) while a resident, two rak'ahs while traveling, and one rak'ah during times of fear."
فَرَضَ اللَّهُ الصَّلاَةَ عَلَى لِسَانِ نَبِيِّكُمْ ﷺ فِي الْحَضَرِ أَرْبَعًا وَفِي السَّفَرِ رَكْعَتَيْنِ وَفِي الْخَوْفِ رَكْعَةً
"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 Salah was enjoined on the lips of the Prophet ﷺ, four Rak'ahs while resident, and two while traveling, and one Rak'ah during times of fear."
فُرِضَتِ الصَّلاَةُ عَلَى لِسَانِ النَّبِيِّ ﷺ فِي الْحَضَرِ أَرْبَعًا وَفِي السَّفَرِ رَكْعَتَيْنِ وَفِي الْخَوْفِ رَكْعَةً
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
