Maryam 19:21

قَالَ كَذَٰلِكِ قَالَ رَبُّكِ هُوَ عَلَىَّ هَيِّنٌ ۖ وَلِنَجْعَلَهُۥٓ ءَايَةً لِّلنَّاسِ وَرَحْمَةً مِّنَّا ۚ وَكَانَ أَمْرًا مَّقْضِيًّا

Qāla kadhāliki qāla rabbuki huwa ʿalayya hayyinun walinajʿalahu āyatan lilnnāsi waraḥmatan minnā wakāna amran maqḍiyyan

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.'"
