Assalaamu alaykum wa Rahmatullahi wa Barakatuh.
Subhaan Allah, those who are blessed with knowledge - beneficial knowledge, aka 'ilm - know the critical importance of "sami'na wa ata'na" - we hear, and we obey. They know that in following Islam, following the Qura'an and the Sunnah, they will have ease without conflict. Why? Because they aren't subject to opinion, personal feelings, or their own interpretation of any matter. They seek the legislated path and they stick to it, with all else being thrown aside or never even coming into play. I wish it for every believing Muslim on this planet - ameen.
Fitna doesn't grow out of Islam. It grows out of the absence of Islam. It grows out of the absence of knowledge and adherence to it. Fitna doesn't grow out of proof and accountability; it grows out of ignorant self-conviction and sheer disobedience. Muslims, new and seasoned, are guilty of this. I went through that stage 30+ years ago and, after making extensive istighfar, I dread reverting to such a state again.
The enormity of the du'a Rabbi zidnee 'ilmaa is that increasing in sound Islamic knowledge frees your mind and heart. You live in peace and security because you are living "sami'na wa ata'na."
Subhaanak Allahumma wa bihamdik laa illaaha ilaa ant, astaghfiruka wa atoobu ilayk.
