Perhaps
in Edition Clear Qur'an by Talal Itani / Al-Kahf (The Cave)

18:6Perhaps you may destroy yourself with grief, chasing after them, if they do not believe in this information.

18:24Without saying, “If God wills.” And remember your Lord if you forget, and say, “Perhaps my Lord will guide me to nearer than this in integrity.”

18:40Perhaps my Lord will give me something better than your garden, and release upon it thunderbolts from the sky, so it becomes barren waste.
