Hadith on Dua: The Prophet asks Allah for light in his heart

Ibn Abbas reported: He spent the night with the Messenger of Allah, peace and blessings be upon him, and he woke up. The Prophet cleansed his teeth, performed ablution, the call to prayer was announced, and he went out for the prayer while he was saying, “O Allah, place light in my heart and light on my tongue. Place light in my hearing and light in my seeing. Place light behind me and light in front of me. Place light above me and light below me. O Allah, grant me light!

عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ أَنَّهُ رَقَدَ عِنْدَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَاسْتَيْقَظَ فَتَسَوَّكَ وَتَوَضَّأَ فَأَذَّنَ الْمُؤَذِّنُ فَخَرَجَ إِلَى الصَّلَاةِ وَهُوَ يَقُولُ اللَّهُمَّ اجْعَلْ فِي قَلْبِي نُورًا وَفِي لِسَانِي نُورًا وَاجْعَلْ فِي سَمْعِي نُورًا وَاجْعَلْ فِي بَصَرِي نُورًا وَاجْعَلْ مِنْ خَلْفِي نُورًا وَمِنْ أَمَامِي نُورًا وَاجْعَلْ مِنْ فَوْقِي نُورًا وَمِنْ تَحْتِي نُورًا اللَّهُمَّ أَعْطِنِي نُورًا
