Qur'an 19:21 · Maryam

قَالَ كَذَٰلِكِ قَالَ رَبُّكِ هُوَ عَلَىَّ هَيِّنٌۭ ۖ وَلِنَجْعَلَهُۥٓ ءَايَةًۭ لِّلنَّاسِ وَرَحْمَةًۭ مِّنَّا ۚ وَكَانَ أَمْرًۭا مَّقْضِيًّۭا

(21) He said, "Thus [it will be]; your Lord says, 'It is easy for Me, and We will make him a sign to the people and a mercy from Us. And it is a matter [already] decreed.'"
