Question:
What is the ruling for learning tajwid?
Answer:
It is Fardh al-‘Ayn (individual obligation) to learn tajwid to such an extent that a letter can be distinguished from another when pronouncing it. Without this, Salah is void. Let alone the average person, even the dignified personalities ignore this obligatory rule as they do not clearly pronounce the Ha (ه) and the Sad (ص) correctly in order to differentiate these letters from the rest.
And Allah ﷻ knows the best
