Hadith.1011 - Ali ibn Nu'man al-Razi narrated that He said: I was traveling with some companions, and I was their Imam (leading the prayer). I led them in Maghrib prayer and mistakenly ended the prayer after two units (rak'ahs). My companions told me that I had only led them in two rak'ahs. We discussed it among ourselves, and they decided that they would repeat their prayer. I, however, decided not to repeat it but to complete it by adding one more rak'ah. So, I completed it with an additional rak'ah, and we then continued our journey. Later, I went to Imam Ja'far Al-Sadiq عليه السلام and told him about what had happened. Imam عليه السلام said to me: "You acted more correctly than they did. Only the one who does not know what he has prayed needs to repeat (the prayer)”. 1012 1012 - وَ رَوَى عَنْهُ عَمَّارٌ: «أَنَّ مَنْ سَلَّمَ فِي رَكْعَتَيْنِ مِنَ اَلظُّهْرِ أَوِ اَلْعَصْرِ أَوِ اَلْمَغْرِبِ أَوِ اَلْعِشَاءِ اَلْآخِرَةِ ثُمَّ ذَكَرَ فَلْيَبْنِ عَلَى صَلاَتِهِ وَ لَوْ بَلَغَ اَلصِّينَ وَ لاَ إِعَادَةَ عَلَيْهِ. Hadith.1012 - Ammar narrated: "Whoever gives the salutation (taslim) after two rak'ahs of the Dhuhr, Asr, Maghrib, or Isha prayers, and then remembers, should continue with their prayer, even if they reach China, and there is no need for them to repeat it”.
