Wahi wāw ḥā yā (و ح ي)? What is it in the Quran's true sense?
Wahi = INSTILL and not reveal or inspire.. but INSTILL ... let's see.. I already brought to light the root of ILM and that has the meaning of Reveal..
3:44 "That is from the information of the profundity that We instill to you.."
The above verse is just an example from numerous verses, but let's concentrate on the below verse in detail..
42:51 "And it was not for a mortal that Allah to communicate to him except instilling (wahi), or from beyond intervention, or dispatching a dispatcher(rasool), then instill (yuhi) what He causes by His leave...."
The Dispatcher from Malak (controller) did not simply come, reveal, or dump and leave to the respective Nabis so that they dispatch/arsal whatever they understand without explaining what it is. Instead, these Malak dispatchers instilled what they brought from Allah to human dispatchers/rasools, but with the leave of Allah as He caused. That's why human Dispatchers—be it Musa, Isa, Mohamed, Ibrahim, or anyone—had perfect knowledge of what to educate (yuthla) to people through what they were instilled with by the Malak dispatchers.
Okay, what is instill? Let's open the dictionary. The word "instill" means to gradually introduce or implant an idea, feeling, habit, or value in someone over time. It often implies a slow and deliberate process of influencing or teaching someone.
However, the Malak Dispatcher may not instill everything but only what Allah causes (Yasha), leaving certain things for the future or others. In that case, those verses are just proper words, but their precise meanings are not known by human dispatchers unless they resolve (iqra) on their own. That's why Allah used in the above verse (42:51) 'Ma Yasha Allah', i.e., 'what Allah causes.' If the verse had ended without 'Ma Yasha Allah' and only said, 'Then instill by His leave,' it could have meant that all Human Dispatchers/Rasools were instilled with EVERYTHING from their respective instilling (wahi), leaving nothing. That did not happen; instead, it was only what Allah caused (note verse 3:7). No human dispatcher was instilled with such verses, but it was their effort to resolve such verses, albeit with the guidance of Allah. This Quran is a profound book, and human Dispatchers would not be able to deal with it within a short period of time and educate people unless they were instilled properly when it was revealed (ilm) to them. Without instilling, it would have become a serious issue for all human dispatchers..
Second point: What about others who were not educated by human dispatchers directly? For instance, people like us who research or study the Quran but were not directly educated (yuthla) by the Human Dispatcher of Allah? Yes, in that case, Allah instills directly. Remember well: INSTILL, not anything else. I mean not the third option in the verse, i.e., MIN WARAI HIJAB / from beyond intervention. Not that. This second option may not involve direct instilling from Allah, but a Malak may be involved whenever one tries to resolve Quran verses. However, the person who receives the instilling is not aware that they are being instilled by Allah through a Malak. In the first option, the person who is instilled knows that the Malak dispatcher instilled them (human dispatchers/rasool). I hope my wording is clear.
The third point is MIN WARAI HIJAB / from beyond intervention. With whom it happens is a mystery, and they and Allah alone know it. For example, Allah communicated to Musa and that has no intervention.
You can apply these criteria to every Quran verse, be it Musa's mother or bees etc.. They are all nothing but INSTILL but the way it is done is through one of the above methods. Even 'from beyond intervention' is INSTILL but, direct instilling..
