What was the special prayer that would be offered by Sa`d, similar to that of Prophet Muhammad (saw)?
 Narrated Jabir bin Samura:                     Sa`d said, "I used to pray with them a prayer similar to that of Allah's Apostle (the prayer of Zuhr and `Asr) reducing nothing from them. I used to prolong the first two rak`at and shorten the last two rak`at." `Umar said to Sa`d "This was what we thought about you."
