She and others (equally destitute - all sinners with bad record) - had no money in their purses to pay the scot. The ferry man did not oblige them with a free lift. They waited in vain till sunset at the sea side. It was only when Allah graciously arranged for them, says Sayed, that they crossed over and reached their destination. (Obviously they were reunited with their Consorts).
Note: A voyager needs cash to meet the voyage expenses. In the above two verses the voyager complained that he had no money and was therefore helpless in the matter of money may mean good deeds and as such the woman was not entitled to a union with her consort. Allah, however, made up her deficiency by His mercy joined her to her beloved.
And it was certainly due from Us to help the believers . (47, Al-Rum).

They had no fare, nor would boatman take them gratis,
Whole day they remained on shore till the sun was set,
Their destination they easily reached, when God's help came.

They had no fare and the ferryman did not take them free,
They waited for whole day at the sea coast till the sun set,
Sayyad say, it was when Lord desired they reached favorable landing.
