quran:44:3 –

Indeed, We sent it down during a blessed night. Indeed, We were to warn ˹mankind˺.  

Indeed We revealed it on a blessed night, the Night of Ordainment (laylat al-qadr), or the eve of the middle of Sha‘bān, in which it was revealed from the Mother Book, from the seventh heaven to the heaven of this world. Indeed We have been warning, We have been causing ˹people˺ by it to have fear ˹of God˺.
القرآن:٤٤:٣ –

إِنَّا أَنْزَلْنَاهُ فِي لَيْلَةٍ مُبَارَكَةٍ ۚ إِنَّا كُنَّا مُنْذِرِينَ  

{إنا أنزلناه في ليلة مباركة} هي ليلة القدر أو ليلة النصف من شعبان، نزل فيها من أم الكتاب من السماء السابعة إلى سماء الدنيا {إنا كنا منذرين} مخوِّفين به.
