"Imran bin Husain was asked about the traveler's prayer. He said: 'I performed Hajj with the Messenger of Allah, and he prayed two Rak'ah. I performed Hajj with Abu Bakr, and he prayed two Rak'ah and with Umar, and he prayed two Rak;ah; and with Uthman for six years of his Khilafah, or eight years, and he prayed two Rak'ah."
حَجَجْتُ مَعَ رَسُولِ اللَّهِ ﷺ فَصَلَّى رَكْعَتَيْنِ وَحَجَجْتُ مَعَ أَبِي بَكْرٍ فَصَلَّى رَكْعَتَيْنِ وَمَعَ عُمَرَ فَصَلَّى رَكْعَتَيْنِ وَمَعَ عُثْمَانَ سِتَّ سِنِينَ مِنْ خِلاَفَتِهِ أَوْ ثَمَانِيَ سِنِينَ فَصَلَّى رَكْعَتَيْنِ
