Surah Al-Qasas, verse 27

قَالَ إِنِّىٓ أُرِيدُ أَنْ أُنكِحَكَ إِحْدَى ٱبْنَتَىَّ هَـٰتَيْنِ عَلَىٰٓ أَن تَأْجُرَنِى ثَمَـٰنِىَ حِجَجٍ ۖ فَإِنْ أَتْمَمْتَ عَشْرًا فَمِنْ عِندِكَ ۖ وَمَآ أُرِيدُ أَنْ أَشُقَّ عَلَيْكَ ۚ سَتَجِدُنِىٓ إِن شَآءَ ٱللَّهُ مِنَ ٱلصَّـٰلِحِينَ ﴿٢٧﴾

28:27 He said, “I would like to give you one of these two daughters of mine in marriage, provided that you serve me for eight years; if you complete ten, it will be of your own free will. I do not want to make things difficult for you. You will find me, if Allah wills, from among the righteous.”
