As-salāmu ʿalaykum wa raḥmatullāhi wa barakātuh, 1) Should one start with Aqeedah Wasitiyyah or Qawaaid al Muthla 2) Best books and shuruuh for Usul al Fiqh after al-Waraqaat and Usul min 'ilm al Usul Jazakallahu ghairan

Ustadh AbdulAziz al-Haqqan

Start with the Wasitiyya and then Qawa'id al-Muthla. As for Usul, wait for the academy when we release the higher level when it comes to Usul, as I don't want you to get confused reading alone.
