Holy cows, okay yall now I am understanding the question of hadithians. Okay so see my main confusion was why the hadithmongers always asked us the question to explain Qiraat and obviously I didn't get the question because why the heck do we need to explain Qiraat. If the message of all Qiraat are same then why do we need to explain Qot right ? As i said i had no idea was Qiraat is, I only got to know it from an argument on YouTube ( i didn't start it of course but I needed to support my submitter brother, hadithmongers were being major pain in the brain ). Only here I got to know the names of two of them : Hafs and Warsh. Well after not finding this question in general issue ( yes i am dumb, i freaking posted it in women's issue smh ) i forgot about it. Well I came here to. Ask some women related question and guess what I saw ? A question about qiraat on women's issue... Yikes kill me 🙃. I am diverting from the topic so anyways, I went through the all of the answers and still didn't understand a thing and then I did a google search Because now i wanted to see how are hadiths and qiraat related. Now after 5 minutes everything is making sense. So there's this hadith which explained everything now,.
I heard Hishām ibn Ḥakīm reciting Sūrah Al-Furqān during the lifetime of Allah's messenger. I listened to his recitation and noticed that he recited in several different ways which the Prophet had not taught me. I was about to jump over him during his prayer, but I was able to contain myself, and when he had completed his prayer, I put his upper garment around his neck and seized him by it and said, “Who taught you this Sūrah which I heard you reciting?” He replied, “The Prophet taught it to me.” I said, “You are wrong, for the Prophet has taught it to me in a different way from yours.”
So I took him to Allah’s Messenger and said “O Messenger of Allah, I heard this individual reciting Sūrah Al-Furqān in a way that you did not teach me, and you have taught me Sūrah Al-Furqān.”
The Prophet said, “O Hishām, recite!” So he recited in the same way as I heard him recite it before. On that Allah's Messenger ﷺ said, “It was revealed to be recited in this way.” Then Allah's Messenger ﷺ said, “Recite, O ʿUmar!” So I recited it as he had taught me. Allah's Messenger ﷺ then said, “It was revealed to be recited in this way.” Allah’s Apostle added, “This Qur’an has been revealed to be recited in seven different aḥruf, so recite it whichever way is easier for you.”
So basically hadithians believe that since Quran doesn't mention about Qiraat and there is a hadith which mentions the 7 huruf and we also have different qiraat therefore it proves the authenticity of hadiths. Wow. My mind just went haywire. And now i do understand their argument and now I am also understanding all of your answers. So basically some amazing person here brought out the old manuscript of Quran *hugs*
