As Salamu Alaikum wa Rahmatullahi wa Barakatuhu The most frequently recited Dua
Narrated by Anas (Radhi Allahu Anhu): The most frequent invocation of The Prophet (Sallallahu Alayhi wa Sallam) was: “Rabbana atina fid-dunya hasanatan wa fil-akhirati hasanatan waquina adhaban-nar"
(Al-Bukhari and Muslim) The disapproval of supplication in which a request is made to Allah for punishment of one's (misdeeds) in the world.
Anas (Radhi Allahu Anhu) reported that Allah's Messenger (Sallallahu Alayhi wa Sallam) visited a person from amongst the Muslims in order to inquire (about his health) who had grown feeble like the chicken. Allah's Messenger (Sallallahu Alayhi wa Sallam) said: “Did you supplicate for anything or beg of Him about that?” He said: “Yes. I used to utter (these words): Impose punishment upon me earlier in this world, what You are going to impose upon me in the Hereafter.” Thereupon Allah's Messenger (Sallallahu Alayhi wa Sallam) said: “Glorified be Allah, you have neither the power nor forbearance to take upon yourself (the burden of His Punishment). Why did you not say this: O Allah, grant us good in the world and good in the Hereafter, and save us from the torment of Fire.
” The Prophet (Sallallahu Alayhi wa Sallam) made this supplication (for him) and he was all right. (Muslim)
