The Quran

رَبَّنا إِنّي أَسكَنتُ مِن ذُرِّيَّتي بِوادٍ غَيرِ ذي زَرعٍ عِندَ بَيتِكَ المُحَرَّمِ رَبَّنا لِيُقيمُوا الصَّلاةَ فَاجعَل أَفئِدَةً مِنَ النّاسِ تَهوي إِلَيهِم وَارزُقهُم مِنَ الثَّمَراتِ لَعَلَّهُم يَشكُرونَ

Muhammad Asad

"O our Sustainer! Behold, I have settled some of my offspring in a valley in which there is no arable land,¹ close to Thy sanctified Temple, so that, O our Sustainer, they might devote themselves to prayer: cause Thou, therefore, people's hearts to incline towards them² and grant them fruitful sustenance, so that they might have cause to be grateful.

I.e., the narrow desert valley of Mecca, which is enclosed by barren, rocky hills. By "some of my offspring" Abraham refers to Ishmael and his descendants who settled at Mecca.
I.e., to be desirous of visiting them - namely, on pilgrimage to Mecca - and thus help them to maintain themselves in the holy but barren land. The phrase af'idah min an-nas lends itself also to the rendering "the hearts of some people", in which case it could be taken to mean "the hearts of the believers" (Baghawi, Razi, Ibn Kathir).
