Ibn ‘Abbas reports that he once stayed the night as a guest of Maymuna, who was his aunt, and the Prophet (salAllahu alayhi wasalam). They slept on their blanket lengthways, and he slept at the end, crossways. After they had all slept for a while, the Prophet rose in the middle of the night to pray the tahajjud prayer, and Ibn ‘Abbas joined him.


They both did wudhu, and he prayed eleven rak'ats with the Prophet (salAllahu alayhi wasalam). Then they both went back to sleep again until dawn. Bilal called the adhân and the Prophet did another two short rak’ats, before going into the mosque to lead the Dawn Prayer.


Ibn ‘Abbas said that one of the du'as that the Prophet made during this night was:

Translation:
"O Allah, place light in my heart, light in my tongue, light in my hearing, light in my sight, light behind me, light in front of me, light on my right, light on my left, light above me and light below me; place light in my sinew, in my flesh, in my blood, in my hair and in my skin; place light in my soul and make light abundant for me; make me light and grant me light."

اللَّهُمَّ اجْعَلْ فِي قَلْبِي نُورًا , وَفِي سَمْعِي نُورًا , وَفِي بَصَرِي نُورًا , وَعَنْ يَمِينِي نُورًا , وَعَنْ شِمَالِي نُورًا , وَأَمَامِي نُورًا , وَخَلْفِي نُورًا , وَفَوْقِي نُورًا , وَتَحْتِي نُورًا , وَاجْعَلْ لِي نُورًا
( أَوْ قَالَ : وَاجْعَلْنِي نُورًا )

Transliteration:
Allahummajal fi qalbi nuura, wa-fi basari nuura, wa-fi samee nuura, wa-ay-yameeni nuura, wa-ay-yasaari nuura, wa-fawqi nuura, wa-tahti nuura, wa-amaami nuura, wakhalfi nuura, wa fawqi nuura, wa tahti nuura, wa'jal li nuuraa
