Whoever intercedes for a good cause will have a reward therefrom; and (4:85)

﴿مَّن يَشْفَعْ شَفَاعَةً حَسَنَةً يَكُن لَّهُ نَصِيبٌ مِّنْهَا ۖ وَمَن يَشْفَعْ شَفَاعَةً سَيِّئَةً يَكُن لَّهُ كِفْلٌ مِّنْهَا ۗ وَكَانَ اللَّهُ عَلَىٰ كُلِّ شَيْءٍ مُّقِيتًا﴾
[ النساء: 85]

4:85 Whoever intercedes for a good cause will have a reward therefrom; and whoever intercedes for an evil cause will have a burden therefrom. And ever is Allah, over all things, a Keeper.

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.

Whosoever intercedes for a good cause will have the reward thereof, and whosoever intercedes for an evil cause will have a share in its burden. And Allah is Ever All-Able to do (and also an All-Witness to) everything.
