عَنْ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ: صَلَاةُ السَّفَرِ رَكْعَتَانِ، وَصَلَاةُ الْأَضْحَى رَكْعَتَانِ، وَصَلَاةُ الْفِطْرِ رَكْعَتَانِ، وَصَلَاةُ الْجُمُعَةِ رَكْعَتَانِ تَمَامٌ غَيْرُ قَصْرٍ عَلَى لِسَانٍ مُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ
Sayyiduna Umar bin Khattab (may Allah be pleased with him) says: The two rak‘ahs of travel prayer, the two rak‘ahs of Eid al-Adha prayer, the two rak‘ahs of Eid al-Fitr prayer, and the two rak‘ahs of Jumu‘ah prayer are complete prayers upon the tongue of Muhammad (peace and blessings be upon him); there is no deficiency in them.
