promise
in Edition Clear Qur'an by Talal Itani / Maryam (Mary)

19:54And mention in the Scripture Ishmael. He was true to his promise, and was a messenger, a prophet.

19:61The Gardens of Eden, promised by the Most Merciful to His servants in the Unseen. His promise will certainly come true.

19:75Say, “Whoever is in error, the Most Merciful will lead him on.” Until, when they see what they were promised—either the punishment, or the Hour. Then they will know who was in worse position and weaker in forces.

19:78Did he look into the future, or did he receive a promise from the Most Merciful?
