What does Alayna Wa Alaykum mean

Learn Attahiyat Full Dua (Attahiyat lillahi wa salawatu)

Now, this is just one version of the Attahiyat, in a separate narration in Sunan Abu Dawud, Sahih (Al-Albani) hadith 971 it is recited as follows:

Transliteration: At-tahiyyaatu Lillaahi, az-zaakiyaatu Lillaahi, al-tayyibaatu Lillaahi, al-salawaatu Lillaahi. As-salaamu ‘alayka ayyuha’n-Nabiyyu wa rahmat-Allaahi wa barakaatuhu. As-salaamu ‘alayna wa‘ alaa ‘ibaad-Illaah is-saaliheen. Ash-hadu an laa ilaaha ill-Allaah wa ash-hadu anna Muhammadan ‘abduhu wa rasooluhu

Translation: All compliments are due to Allaah, all pure things are due to Allaah, all pure words are due to Allaah, all prayers are due to Allaah. Peace be upon you, O Prophet, and the mercy of Allaah and His blessings. Peace be upon us, and on the righteous slaves of Allaah. I bear witness that none has the right to be worshiped except Allaah, and I bear witness that Muhammad is His slave and Messenger.

Which of the two versions of should you recite?

Since the wordings are different and the final tashadud can only be recited once which version should you recite, bukhari or abu dawood?

The answer is to learn attahiyat of both versions and alternate between the two. Maybe for fajr, dhur, maghrib one day you say bukhari version of attahiyat and for asr and isha you read abu dawood. This would be up completely up to you.

In learning both, you will have completed all the Sunnah of Prophet Muhammad (saws) when it comes to tashadud. Why limit yourself with only reciting one way.

Now, if it is difficult for you, then do what your able to do. Stick with whichever version you were taught when you learned to pray salat, there is no sin by saying one over the other or not saying the other at all.
