Caution: Translations of Quran and Ḥadīth may lead to possible misapplications and misinterpretations. This site is intended for students of sacred knowledge that are proficient in comprehending classical Arabic and have a strong foundation in Islamic sciences. Also note that religious injunctions rely on several aspects beyond what one may glean through reading individual aḥādīth.
quran:20:17

And what is that in your right hand, O Moses?"  

And what is that, that happens to be, in your right hand, O Moses?’ (the interrogative is meant as an affirmative, ˹but it is expressed as an interrogative˺ in order that the miracle ˹to be manifested˺ in it be ˹shown as˺ consequent upon it).
القرآن:٢٠:١٧

وَمَا تِلْكَ بِيَمِينِكَ يَا مُوسَىٰ  

{وما تلك} كائنة {بيمينك يا موسى} الاستفهام للتقرير ليرتب عليه المعجزة فيها.
