‎ أحسنَ اللهُ إليكم sheikh what should i prioritize in my hifz, the adilla from quran and hadeeth in the books we study, the must to know hadeeth like 40 nawawiya or the general hifz to become a hafiz, baarakallahufikom

These are all valid and they do not contradict one another. Some people prefer to do general hifz like Qur'an juz' by juz' and the 40 nawawi hadeeth which is valid. Some like to do it in accordance with the lessons learned. So, choose which one works for you best in sha'a Allah.
