1 verse has
heavily
in Edition Clear Qur'an by Talal Itani / At-Tawba (The Repentance)

9:38O you who believe! What is the matter with you, when it is said to you, “Mobilize in the cause of God,” you cling heavily to the earth? Do you prefer the present life to the Hereafter? The enjoyment of the present life, compared to the Hereafter, is only a little.
