Sis intention was not made vocally , out loud or otherwise by any sahabi or the prophet sala lahu alihi wa sallam himself , this is an innovation ,. there is no HADEETH to indicate it , not even a false n fabricated hadeeth nor a weak hadeeth , there is is NO evidence of doing that whatso ever.
Its all in the heart , for example if i leave my house to go to pray fajr , thats my niyah right there , now when i get to the masjid may be my niyyah from home was that i will pray 2 rakat tahiyatul masjid or sunnah of fajr ( if i have not prayed it at home) but when i get there i see them getting ready for the salah , so all of a sudden my niyah in my heart changes n instead of me praying those two rakats my niyah in my heart becomes that i will join them in obligatory salah and later i can pray the sunnah InshahAllah.
I do not have to say vocally that " I intend to pray two rakat farz namaz of fajr behind an imam facing the kaaba shareef -- Allah hu akbar!
Have u seen this brothes n sisters , i always every day in each salah see this , people cpome stand in the row n keep mumbling stuff and most of the times they lose out on joining the imam in takbeer tahrimah , the frst tabeer and the imam starts the faathia and they lose the ajar of joining from the first takbeer? why coz of a bidah an innovation that the Prophet sala lahu alihi wa sallam never practise , never taught m never legislated , never did his sahabas.
I also see sometimes peole are ina hurry n they mae the wrong niyah , like imsated of dhur namaz they say asr namaz for example n By Allah i have seen them break their salah again and start over with announcing n uttering out the right niyyah ,and this is a common site in many masajid
U see some keep their hands on their ears for almost aminute or more or like half a minute n some even get stuck in that position for longer , have u not seen this brothers? a guy standing to pray and he takes his hands up to his ears fp rthe takbeer n they stay there for quite some time coz he cant get the niyyah right , thre rakat no noastaghfiruul , two rakah fajr , no astaghirullah 4 rakat sunnah dhur and on and on.
Who ever claims that niyah is to be said before the salah , Please bring ur evidence , we are not the ones supposed to bring the evidence , rather the one who has legislated the action has to brig the evidence fro his action , coz evidence is always for an act or action , so please bring the evidence that the prophet sala lahu alihi wa sallam did it or taught it n NO general ahadeeth do not apply it has to be specific , so dont bring the hadeeth that " inna mal amaal bi niyat"
that is a general hadeeth .and doe snot in any way apply to reading teh niyyah , out loud or softly or any other way , rather niyah is in the heart.
I dont know how u missed the reply of mujaheeda , she brought evidence rom a well know scholar , please do check it.
Here is another way of understanding it.
We see that the pathan brothers so the niyyah in pashtu , the bangla do it in bangla , the urdu speaking say it in urdu , the arabic (some of them ) say it in arabic ,
So i ask , If the Prophet sala lahu alihi wa sallam had done it in arabic , wouldnt the same words apply to us all?? and wouldnt than we all have to do it in arabic coz it was a part of the salah , just like a pathaan cannot recite surah al fathiha's translation in pashtu we wont be able to do it in our own languages.
hope it helps
and hope no one minds , may Allah bless u all , n reward u all.
