Ibrahim (AS) prayed the following Dua for his children and family:

رَبَّنَا لِيُقِيمُوا الصَّلاةَ فَاجْعَلْ أَفْئِدَةً مِنَ النَّاسِ تَهْوِي إِلَيْهِمْ وَارْزُقْهُمْ مِنَ الثَّمَرَاتِ لَعَلَّهُمْ يَشْكُرُونَ

Rabbanaa liyuqeemus-Salaata faj'al af'idatam-minan-naasi tahweee ilaihim warzuqhum minath-thamaraati la'allahum yashkuroon.

Our Lord, I have settled some of my descendants in an uncultivated valley near Your sacred House, our Lord, that they may establish prayer. So make hearts among the people incline toward them and provide for them from the fruits that they might be grateful.
