Whoever guides someone to good has a reward like the one who does it.
Sahih Muslim · 1893
اللَّهُمَّ اجْعَلْ فِي قَلْبِي نُورًا، وَفِي بَصَرِي نُورًا، وَفِي سَمْعِي نُورًا، وَعَنْ يَمِينِي نُورًا، وَعَنْ يَسَارِي نُورًا، وَفَوْقِي نُورًا، وَتَحْتِي نُورًا، وَأَمَامِي نُورًا، وَخَلْفِي نُورًا، وَاجْعَلْ لِي نُورًا.
Allāhumma ijʿal fī qalbī nūran, wa fī baṣarī nūran, wa fī samʿī nūran, wa ʿan yamīnī nūran, wa ʿan yasārī nūran, wa fawqī nūran, wa taḥtī nūran, wa amāmī nūran, wa khalfī nūran, wajʿal lī nūrā.
O Allah, place light in my heart, my sight, and my hearing; place light on my right and my left, above me and below me, before me and behind me; and grant me light.
