Sunan Ibn Majah, 1071

It was narrated from ‘Isa bin Hafs bin ‘Asim bin ‘Umar bin Khattab that his father told him:“We were with Ibn ‘Umar on a journey, and he led us in prayer. Then we finished with him and he finished turning around, and saw some people praying. He said: ‘What are these people doing?’ I said: ‘Glorifying Allah.’* He said: ‘If I wanted to glorify Allah (perform voluntary prayer) I would have completed my prayer. O son of my brother! I accompanied the Messenger of Allah (ﷺ) and he never prayed more than two Rak’ah when he was traveling, until Allah took his soul. Then I accompanied Abu Bakr and he never prayed more than two Rak’ah (when he was traveling), until Allah took his soul. Then I accompanied ‘Umar and he never prayed more than two Rak’ah, until Allah took his soul. Then I accompanied ‘Uthman and he never prayed more than two Rak’ah, until Allah took his soul. Allah says: ‘Indeed in the Messenger of Allah (Muhammad (ﷺ)) you have a good example to follow.’” [33:21] * Meaning, they were offering voluntary prayer

Rapporté par ‘Isa bin Hafs bin ‘Asim bin ‘Umar bin Khattab : Son père lui a raconté : “Nous étions en voyage avec Ibn ‘Umar, et il nous a dirigés dans la prière. Après avoir terminé, il s’est retourné et a vu des gens en train de prier. Il a demandé : ‘Que font ces gens ?’ J’ai répondu : ‘Ils glorifient Allah.’ Il a dit : ‘Si je voulais glorifier Allah (faire une prière surérogatoire), j’aurais complété ma prière. Ô fils de mon frère ! J’ai accompagné le Messager d’Allah (ﷺ) et il n’a jamais prié plus de deux rak’ah en voyage, jusqu’à ce qu’Allah prenne son âme. J’ai ensuite accompagné Abu Bakr, et il n’a jamais prié plus de deux rak’ah en voyage, jusqu’à ce qu’Allah prenne son âme. Puis j’ai accompagné ‘Umar, et il n’a jamais prié plus de deux rak’ah, jusqu’à ce qu’Allah prenne son âme. J’ai aussi accompagné ‘Uthman, et il n’a jamais prié plus de deux rak’ah, jusqu’à ce qu’Allah prenne son âme. Allah dit : ‘En effet, vous avez dans le Messager d’Allah (Muhammad (ﷺ)) un excellent exemple à suivre.’” [33:]
