Sayyiduna Abu Umamah (May Allah be pleased with him) reported:
The Messenger of Allah (sallAllaahu alaihi wasallam) made many supplications which we did not memorize. We said to him:
“O Messenger of Allah! (sallAllaahu alaihi wasallam) You have made many supplications of which we do not remember anything.”

The Messenger of Allah (sallAllaahu alaihi wasallam) said, “Should I not show you such a comprehensive dua that includes all duas? Say,


A comprehensive dua that includes all duas

 

(O Allah, I beg to You the good which Your Prophet Muhammad (sallAllaahu alaihi wasallam) begged of You;
and I seek refuge in You from the evil where from Your Prophet Muhammad (sallAllaahu alaihi wasallam) sought refuge.
You are the One from Whom help is sought and Your is the responsibility to communicate (the truth). There is no power or strength except with Allah the Exalted, the Great.”’
[At-Tirmidhi]

Commentary:
For those who do not remember many prayers, or cannot remember them, this is the best supplication to make. This shows part of Allah’s Mercy upon his slaves and part of the easiness of practicing Islam.
