Hawzah News Agency - Imam al-Sadiq (a) says:

إنَّ اللَّهَ جلَّ ثَناؤهُ خَلَقَ العَقلَ، وهُوَ أوَّلُ خَلقٍ خَلَقَهُ مِنَ الرُّوحانيّينَ عَن يَمينِ العَرشِ مِن نورِهِ.

‘Verily Allah, exalted be His praise, created the intellect, and it is the very first thing He created amongst all the spiritual beings from the right hand side of His Throne out of His Light.’
