مَنْ يَّشْفَعْ شَفَاعَةً حَسَنَةً يَّكُنْ لَّهٗ نَصِيْبٌ مِّنْهَا ۚ وَمَنْ يَّشْفَعْ شَفَاعَةً سَيِّئَةً يَّكُنْ لَّهٗ كِفْلٌ مِّنْهَا ۗ وَكَانَ اللّٰهُ عَلٰى كُلِّ شَيْءٍ مُّقِيْتًا ( النساء: ٨٥ )
Mai yashfa' shafaa'atan hasanatay yakul lahoo naseebum minhaa wa mai yashfa' shafaa'tan saiyi'atanny-yakul lahoo kiflum minhaa; wa kaanal laahu 'alaa kulli shai'im Muqeetaa (an-Nisāʾ 4:85)
Sahih International:
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 Allah, over all things, a Keeper. (An-Nisa [4] : 85)
1 Mufti Taqi Usmani
Whoever makes a good recommendation, there shall be for him a share from it (in the Hereafter), and whoever makes a bad recommendation, there shall be for him a share from it. Allah is powerful over everything.
