Namaz er por dua korar somoy haat tola niye matabhed - ki korbo?

Assalamu Alaikum bhaira, apnara kemon achen? Ami Rangpur theke bolchi. Amar ekta proshno ache ja amar mone onek din dhore ghurpaak khacche. Namaz shesh korar por dua korar somoy haat tole munajat kora niye amader mohollae onek matabhed dekhi. Keu bolen eta sunnah, abar keu bolen farz namaz er por erokom haat tole dua korar kono dalil nai. Amader masjid er imam saheb ek rokom bolen, kintu YouTube e alada alada alemer lecture e alada kotha shuni. Apnader kache jodi kono authentic reference thake, tahole please share koren. Inshallah shothik bujhte parbo. Jazakallah khair 🤲
