Explanation: “And fear Allah, for Allah is severe in punishment”

The Shaykh : Fear Allah such that you do not leave off cooperation in righteousness and piety, or engage in cooperation in sin and aggression. That is, fear Allah by cooperating in righteousness and piety and refraining from cooperating in sin and aggression. Allah is severe in punishment. The connection of this threatening phrase to what came before is very clear, meaning He will punish you if you do not fear Him.
