Is a teacher needed to learn qirāˀāt? Can one learn it themselves just as they learn tajwīd? Can they practise themselves and then never use it until they read to a teacher? Also I have in mind riwāyaẗu shuˁbaḧ which I think is very easy to learn

Ustadh AbdulAziz al-Haqqan

Do both that's how u learn.
