Sami'allaahu liman hamidah, Rabbanaa wa lakal-hamd (Allah hears whoever praises Him. Our Lord, praise is Yours). Every Muslim knows this dua by heart as it is recited in the five daily salahs upon rising from the rukoo. Reciting this dua upon rising from the rukoo is a wajib, must, component of salah. Forgoing this step knowingly will make your salah incomplete. Apart from being essential to the completion of Salah, this dua is a preamble, a beautiful way to gain Allah's attention. The believer seeks to divert Allah's attention towards them by stating that Allah hears whoever praises HIM. O Lord, all praises are yours; look upon me as I kneel and prostrate in prayer and answer my prayers.
The dua for upon rising from the rukoo has been reiterated time and again by the Prophet Muhammad(ﷺ) as found in various hadith. The dua voices the glory of Allah (سُبْحَانَهُ وَتَعَالَى) and declares that all praises and good words are for Him (Sahih al-Bukhari 799). The same has been reported in (Sunan an-Nasa'i 931), where the Prophet Muhammad (ﷺ) told a sahabi who recited the second part of this dua that this dua is so pleasing to Allah that 30-odd angels hastened to write down the man's good deeds in an attempt to be the first. The same has been reported in ( Sunan an-Nasa'i 1062).

Sami'allaahu liman hamidah.
Allah a entendu celui qui L'a loué. »
Rabbanaa wa lakal-hamd, hamdan i katheeran tayyiban mubaarakanfeeh.
« Ô Seigneur ! A Toi la louange, une louange abondante, pure et bénie. »
Mil'as-samaawaati wa mil 'al-'ardhi wa maa baynahumaa, wa mil 'a maa shi'ta min shay 'in ba'd. 'Ahlath-thanaa'i walmajdi, 'ahaqqu maa qaalal-'abdu, wa kullunaa laka 'abdun. Allaahumma laa maani'a limaa 'a'tayta, wa laa mu'tiya limaa mana'ta, wa laa yanfa'uthal-jaddi minkal-jadd.
« Plein les cieux et plein la terre et ce qu'il y a entre les deux. Et plein de tout ce que Tu voudras au-delà de cela. Tu es digne d'éloges et de grandeur, c'est la parole la plus véridique que le serviteur puisse dire et nous sommes tous Tes serviteurs. Nul ne peut retenir ce que Tu as donné et nul ne peut donner ce que Tu as retenu. Le fortuné ne trouvera dans sa fortune aucune protection efficace contre Toi. »
