Ali bin Abi Talib narrated that :
when the Messenger of Allah would stand for the obligatory prayer, he would raise his hands to the level of his shoulder, and he would do this [also] when he finished his recitation and intended to bow, and he would do it when he raised his head from Ruku`, and he would not raise his hands in any of his prayers while he was seated. When he would rise from the two prostrations, he would likewise raise his hands, and say the Takbir, and when he opened his Salat after the Takbir, he would say: โI have directed my face towards the One who has created the heavens and the earth, as a Hanif, and I am not of the idolaters. Indeed, my Salat, my sacrifice, my living, my dying, is for Allah, the Lord of all that exists, without partner, and with this have I been ordered and I am of the Muslims. O Allah, You are the King, there is none worthy of worship except You. Glorified are You, You are My Lord, and I am Your slave, I have wronged myself and I admit to my sin, so forgive me all my sins, verily, there is none who forgives sins but You, and guide me to the best of manners, none guides to the best of them except You, and turn away from me the evil of them, none turns away from me the evil of them except You, I am here in Your obedience and aiding Your cause, and I am reliant upon You and ever-turning towards You, [and] there is no refuge from You nor hiding place from You except (going) to You, I seek Your forgiveness, and I repent to you (Wajjahtu wajhiya lilladhฤซ faแนญaras-samฤwฤti wal-arแธa แธฅanฤซfan wa mฤ ana min al-mushrikฤซn, inna แนฃalฤtฤซ wa nusukฤซ wa maแธฅyฤya wa mamฤtฤซ lillฤhi rabbil-`ฤlamฤซn, lฤ sharฤซka lahลซ wa bidhฤlika umirtu wa ana min al-muslimฤซn. Allฤhumma antal-maliku lฤ ilฤha illฤ ant, subแธฅฤnaka anta rabbฤซ, wa ana `abduka แบalamtu nafsฤซ wa`taraftu bidhanbฤซ faghfirlฤซ dhunลซbฤซ jamฤซ`an, innahลซ lฤ yaghfir adh-dhunลซba illฤ ant.

Labaika wa sa`daika, wa ana bika wa ilaika, [wa] lฤ manjฤ minka wa lฤ maljaโa illฤ ilaik, astaghfiruka wa atลซbu ilaik).โ Then he would recite, then when he would bow, his speech in his Ruku`, would be to say: โO Allah, to You have I bowed, and in You have I believed, and to You have I submitted (in Islam), and You are my Lord. My hearing, my sight, my brain and my bones are humbled to Allah, the Lord of the Worlds all that exists (Allฤhumma laka raka`tu wa bika ฤmantu wa laka aslamtu wa anta rabb ฤซ. Khasha`a sam`ฤซ wa baแนฃarฤซ wa mukhkhฤซ wa `aแบmฤซ lillฤhi, rabbil-`ฤlamฤซn).โ Then, when he raised his head from Ruku he would say: โAllah hears the one who praises him (Sami`a Allฤhu liman แธฅamidah).โ Then he would follow it with: โO Allah, our Lord, to You is praise filling the heavens and the earth and filling whatever You wish of things afterward (Allฤhumma rabbanฤ wa lakal-แธฅamdu milโas-samฤwฤti wal-arแธi, wa milโa mฤ shiโta min shayโin ba`d.).โ Then, when prostrated he would say in his prostration: โO Allah, to You have I prostrated, and in You have I believed, and to You have I submitted (in Islam), and You are my Lord, my face has prostrated to the One that created it, and granted its hearing and sight, Blessed is Allah, the Best of Creators (Allฤhumma laka sajadtu wa bika ฤmantu wa laka aslamtu wa anta rabbฤซ, sajada wajhi lilladhฤซ khalaqahลซ wa shaqqa sam`ahลซ wa baแนฃarahลซ, tabฤrak Allฤhu ahsanul-khฤliqฤซn).โ When he was finished with his Salat, we would say: โO Allah, forgive me what I have done, before and after, and what I have hidden, and what I have done openly, and You are my Deity, there is none worthy of worship except You (Allฤhummaghfirlฤซ mฤ qaddamtu wa mฤ akhkhartu wa mฤ asrartu wa mฤ a`lantu, wa anta ilฤhฤซ lฤ ilฤha illฤ ant).โ
