Raising Both the Hands and Making Dua After Salah

It is narrated that Abdullah Ibn Zubair (radhiallahu anhu) saw a man raising his hands and making dua before completing his salah. When the person had completed his salaah, Hazrat Abdullah Ibn Zubair (radhiallahu anhu) went up to him and said: "Verily, Rasulullah (sallallahu alaihi wasallam) used to only raise his hands and make dua after completing his salaah" (the narrators of this Hadith are all trustworthy — Majmauz Zawaaid, vol. 1, pg. 169).
