قَالَ إِنِّىٓ أُرِيدُ أَنْ أُنكِحَكَ إِحْدَى ٱبْنَتَىَّ هَٰتَيْنِ عَلَىٰٓ أَن تَأْجُرَنِى ثَمَٰنِىَ حِجَجٍۢ ۖ فَإِنْ أَتْمَمْتَ عَشْرًۭا فَمِنْ عِندِكَ ۖ وَمَآ أُرِيدُ أَنْ أَشُقَّ عَلَيْكَ ۚ سَتَجِدُنِىٓ إِن شَآءَ ٱللَّهُ مِنَ ٱلصَّٰلِحِينَ
He said: Lo! I fain would marry thee to one of these two daughters of mine on condition that thou hirest thyself to me for (the term of) eight pilgrimages. Then if thou completest ten it will be of thine own accord, for I would not make it hard for thee. Allah willing, thou wilt find me of the righteous.
