“Stay away from malicious gossip and fake words" (Qur'an 68;11).
This is one of the most brilliant lectures I’ve heard. It’s by Ustadh Nouman Ali Khan, wherein he gives an explanation (tafsir) of the famous verse in Surah Nur, “Allahu nurus samaawaati wal ard… nurun alaa nur..”.
You’ll love it, it might just change your life.
I have a recitation video which includes this verse. It’s the first verse in this recitation from Surah Nur (chapter 24) verses 35.
