مَّن يَشْفَعْ شَفَـٰعَةً حَسَنَةً يَكُن لَّهُۥ نَصِيبٌ مِّنْهَا ۖ وَمَن يَشْفَعْ شَفَـٰعَةً سَيِّئَةً يَكُن لَّهُۥ كِفْلٌ مِّنْهَا ۗ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ مُّقِيتًا ۝٨٥

4:85 Whoso interveneth in a good cause will have the reward thereof, and whoso interveneth in an evil cause will bear the consequence thereof. Allah overseeth all things.
