DU’A AFTER DURUD (BEFORE SALUTATION)
In his Mustadrak, Hakim has reported that (Hadrat) Abdullah-bin-Mas’ud (Radi Allaahu Ta’ala Anhu) suggested that the worshipper should recite the durud after tashahhud and then should recite the supplication. In another tradition reported by Hadrat Abdullah bin Mas’ud appearing in Sahih Muslim and Sahih Bukhari regarding the tashahhud, the last sentence is “Then he may choose any supplication, which pleases him and offer it.
Reciting a suplication (du’a) at the tashahhud after durud is confirmed both by the teaching and the practice of the Prophet (Sallallahu Alaihi Wa Sallam) Hadrat Abu Hurairah (Radi Allaahu Ta’ala Anhu) narrated that the Prophet (Sallallahu Alaihi Wa Sallam) said: When one of you finishes the last tashahhud he should seek refuge in ALLAH from four things.
