Introducing a new religious rite is different from adopting a new tool for an already legitimate activity. The question is whether something is being declared a devotional requirement or is simply a means of facilitating established worship or education.
Example 1: Inventing additional obligatory units of prayer is a religious claim requiring proof.
Example 2: Using a projector or mobile application to teach hadith is an educational tool, not automatically a new act of worship.
Example 3: Where recognized juristic differences exist, investigate them through qualified learning.
مَا لَيْسَ مِنْهُ points to the key test: does the claim genuinely belong to established religious guidance?
