Sahih Muslim · Hadith 1602

حدثنا يحيى بن يحيى، قال قرأت على مالك عن صالح بن كيسان، عن عروة بن الزبير، عن عائشة، زوج النبي صلى الله عليه وسلم أنها قالت فرضت الصلاة ركعتين ركعتين في الحضر والسفر فأقرت صلاة السفر وزيد في صلاة الحضر ‏.‏

'A'isha, the wife of the Messenger of Allah (may peace be upon him), reported: The prayer was prescribed as two rak'ahs, two rak'ahs both in journey and at the place of residence. The prayer while travelling remained as it was (originally prescribed), but an addition was made in the prayer (observed) at the place of residence.
