وَقَالَ الَّذِي نَجَا مِنْهُمَا وَادَّكَرَ بَعْدَ أُمَّةٍ أَنَا أُنَبِّئُكُم بِتَأْوِيلِهِ فَأَرْسِلُونِ (45)
(12:45) Then one of the two prisoners who had been released emembered the dung after a long time and said, "I will tell you its interpretation: just send me (to Joseph in the prison. *38 )"
*38) The Qur'an has told in brief the essence of the request of the chief butler, but the Bible and the Talmud have given its details. According to these (and it stands to reason that it must have been so), he told the king of the life of Prophet Joseph in prison and how he interpreted their dreams rightly and prayed the king to give hits leave to see Prophct Joseph in prison for that purpose.
