Volume 1, Book 12, Number 737:
Narrated Jabir bin Samura:
‘Umar said to Sa’d, “The people complained against you in everything, even in prayer.” Sa’d replied,
“Really I used to prolong the first two Rakat and shorten the last two and I will never shorten the
prayer in which I follow Allah’s Apostle.” ‘Umar said, “You are telling the truth and that is what I
think a tout you.”
