﴿ أَلَّا تَتَّبِعَنِ ۖ أَفَعَصَيْتَ أَمْرِى ﴾

“from [abandoning them and] following me? Hast thou, then, [deliberately] disobeyed my commandment?"”

(That thou followedst me not) that you failed to follow my advice and fight against them? (Hast thou then disobeyed my order) have you then discarded my advice?
