صَلاَةُ الْجُمُعَةِ رَكْعَتَانِ وَصَلاَةُ الْفِطْرِ رَكْعَتَانِ وَصَلاَةُ الأَضْحَى رَكْعَتَانِ وَصَلاَةُ السَّفَرِ رَكْعَتَانِ تَمَامٌ غَيْرُ قَصْرٍ عَلَى لِسَانِ مُحَمَّدٍ صلى الله عليه وسلم .
It was narrated from 'Abdur-Rahman bin Abi Laila that 'Umar said: "Jumu'ah prayer is two rak'ahs, and the prayer of Al-Fitr is two rak'ahs, and the prayer of Al-Adha is two rak'ahs, and the prayer when traveling is two rak'ahs, complete and not shortened, on the tongue of Muhammad (ﷺ)."
