﴿ وَٱمْرَأَتُهُۥ قَآئِمَةٌۭ فَضَحِكَتْ فَبَشَّرْنَٰهَا بِإِسْحَٰقَ وَمِن وَرَآءِ إِسْحَٰقَ يَعْقُوبَ ﴾

“And his wife, standing [nearby], laughed [with happiness]; whereupon We gave her the glad tiding of [the birth of] Isaac and, after Isaac, of [his son] Jacob.”

(And his wife) Sarah, (standing by) to serve them, (laughed) in astonishment that Abraham was afraid (when We gave her good tidings (of the birth) of Isaac, and, after Isaac, of Jacob) a grandchild.
