What is the meaning of the word "Af'idah" (أفئدة) in the noble verse: {Our Lord, indeed I have settled some of my offspring in an uncultivated valley near Your sacred House, our Lord, that they may establish prayer. So make hearts among the people incline toward them}?

A Muslim must verify matters concerning the Book of Allah, as the verse in the question was distorted. The correct text of the verse is: "Our Lord, I have settled some of my offspring 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 them with fruits that they may be grateful." {Ibrahim: 37}. And "hearts" (أفئدة) here means "hearts."
