Qur'an 4:85

مَّن يَشْفَعْ شَفَـٰعَةً حَسَنَةً يَكُن لَّهُۥ نَصِيبٌ مِّنْهَا ۖ وَمَن يَشْفَعْ شَفَـٰعَةً سَيِّئَةً يَكُن لَّهُۥ كِفْلٌ مِّنْهَا ۗ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ مُّقِيتًا

“Whoever intercedes for a good cause will have a share [i.e., reward] therefrom; and whoever intercedes for an evil cause will have a portion [i.e., burden] therefrom. And ever is Allāh, over all things, a Keeper.”
