Al-Mukhtasar
مَّن يَشْفَعْ شَفَـٰعَةً حَسَنَةً يَكُن لَّهُۥ نَصِيبٌ مِّنْهَا ۖ وَمَن يَشْفَعْ شَفَـٰعَةً سَيِّئَةً يَكُن لَّهُۥ كِفْلٌ مِّنْهَا ۗ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ مُّقِيتًا ﴿٨٥﴾
Whoever intercedes or directs another person to some good them in a manner containing no sin or oppression, will receive a share of the reward of the good outcome; and whoever makes a bad intercession, which contains sin or oppression, will receive a share of the sin. Allah watches everything that a person does and will reward him accordingly. So if you become a means of goodness, you will receive a share in that good; and if you become a means of doing evil, you will be guilty for a part of it.
