Hawzah News Agency - Muhammad ibn al-Hassan has narrated from Sahl ibn Ziyad from ibn abu Najran from al-‘Ala’ ibn Razin from Muhammad ibn Muslim that Abu Ja’far (al-Baqir)  said: 

قَالَ لَمَّا خَلَقَ الله الْعَقْلَ قَالَ لَهُ أَقْبِلْ فَأَقْبَلَ ثُمَّ قَالَ لَهُ أَدْبِرْ فَأَدْبَرَ فَقَالَ وَعِزَّتِي وَجَلالِي مَا خَلَقْتُ خَلْقاً أَحْسَنَ مِنْكَ إِيَّاكَ آمُرُ وَإِيَّاكَ أَنْهَى وَإِيَّاكَ أُثِيبُ وَإِيَّاكَ أُعَاقِبُ.

“When Allah (swt) created the intellect (al-'Aql) He made it speak and said to it, ‘Come forward', so it came forward. He then said, 'Go back' and it went back. Then Allah said, 'I swear by My Honor and Glory that I have not created any creation more beloved to Me than you. I will not perfect you in anyone except those whom I love. I will command you [to obey me] and prohibit you [from disobeying me] and I will reward you [for obeying me] and I will punish you [for disobeying me].'"
