Cov lus thov uas yuav tsum tau ua thaum tsaus ntuj tom qab kev thov ntuj thib tsib yog hu ua namaz vitr. Tus Tub xa xov ntawm Huab Tais (txoj kev thaj yeeb nyab xeeb rau nws) tau ua qhov kev thov no tom qab isha (yuav tsum muaj kev pe hawm hmo ntuj) rau lub sijhawm sib txawv ntawm hmo ntuj. Zoo li yav tsaus ntuj Maghreb, lawv hais dab tsi rau Vitr qhov kev thov hauv peb rakagats. Nyeem ntawv Witr lus thov yog wajib (yuav tsum tau).
Qhov kev thov Vajtswv no nyeem zoo ib yam li seem rau seem. Txawm li cas los xij, hauv rakagat thib peb, tom qab nyeem ntawv Al-Fatiha surah thiab tom qab nws luv luv surah, takbir rov qab hais dua ntxiv nrog kev tsa ntawm txhais tes ib yam li thaum pib thov Vajtswv. Tom qab ntawd, txhais tes tau tso dua li niaj zaus (poj niam nyob ntawm lub hauv siab, thiab tus txiv neej nyob hauv qab ntaws), dua "Kunut" tau nyeem thiab qhov kev pehawm no xaus rau txhua yam ntxiv - attahiyat, salavat thiab salam hauv ob qho kev qhia. Nov yog qhov sib txawv ntawm cov lus thov ntawm no thiab lwm tus.
Ntawm no nws yog xav nyeem nyob rau hauv thawj zaug rakagat tom qab "Al-Fatih" sura "Al-Alya" (lub hwjchim loj tshaj plaws), nyob rau hauv lub thib ob rakagat sura "Kafirun" (Infidels) hauv lub thib peb "Ikhlas" (Lub siab dawb paug). Los ntawm Ubay ibn Qagba (kev thaj yeeb thiab koob hmoov ntawm Allah yuav rau nws) nws yog narrated tias tus Yaj Saub nws tus kheej (kev thaj yeeb thiab koob hmoov ntawm Allaah yuav rau nws) nyeem txoj kev no. Nws tseem paub los ntawm lwm cov hadiths uas nws nyeem suras Ikhlas (Sincerity), Falak (Kaj ntug) thiab Nas (Tib neeg). Qhov no yog Sunnah. Koj tuaj yeem nyeem lwm suras yog tias koj nyiam. Cov lus thov nws tus kheej nyeem tsuas yog nyeem rau tus kheej, qhov "Qunut" dua thiab.
Hauv lub hlis dawb huv ntawm Ramadan, Vitr tau nyeem dua imam nrog jamaat (zej zog) tom qab Taraweeh cov lus thov. Ntxiv rau qhov kev thov ntuj Vitr, dua Qunut tau hais rov qab thaum tib neeg muaj kev phom sij. Hauv qhov no, tus imam nyeem dua Qunut tom qab khoov ntawm lub duav thiab nug txog Allah Huab Tais kom pab rau cov neeg ntseeg thiab thov kom muaj kev foom rau cov yeeb ncuab.
