maa shaa Allaah, Allaahuma barek!

Barakallah feekum ya Shaykh

Excellent lesson Subhanallah, may Allah reward our teachers

If we say the Qiraat "emerged" after a certain time are we saying that the sahaba didn't recite these?

Also to those who say that Uthman radiallahu anhu got rid of the Ahruf except for the dialect of Qareysh that can't be because why do we still have 10 Qiraat ?

The Qiraat reflect not only differences in pronunciation, but in spelling, word order , sometimes adding or omitting words and with different meanings, differences in grammar etc.

May Allah reward this Shaykh but sometimes this matter becomes more confusing depending on how it is explained.

Who's he?
