There is the story of Yusuf, the son of Yaqub, to which a Surah of the Quran is dedicated and it recounts how he was hidden from his father, an apostle who received revelations day and night, yet the news of his son was hidden from him and his sons, who would meet him and transact with him, but do not recognize him. Years passed like that before Allah revealed his story and united him with his father and brothers. Such an event is extraordinary and we have not heard the like of it.
