[1018] 159 - (...) It was narrated that Abû ‘Awn said: “I heard Jâbir bin Samurah say: “Umar said to Sa’d: “They are complaining about you in everything, even in prayer.” He said: “I make it long in the first two (Rak’ah) and I make it short in the last two. I do not neglect to follow the example of the prayer of the Messenger of Allâh ﷺ.” He said: “That is what I thought of you.”
