سَجَدَ لَكَ خَيَالِي وَسَوَادِي، وَآمَنَ بِكَ فُؤَادِي، فَهَذِهِ يَدَيَّ وَمَا جَنَيْتُ بِهَا عَلَى نَفْسِي، يَا عَظِيمُ يُرْجَى لِكُلِّ عَظِيمٍ، يَا عَظِيمُ اغْفِرِ الذَّنْبَ الْعَظِيمَ، سَجَدَ وَجْهِيَ لِلَّذِي خَلَقَهُ وَشَقَّ سَمْعَهُ وَبَصَرَهُ
Note: This du'a is specific to sajdah.
My mind and body have prostrated (and submitted) for You, and my heart has brought imaan in You. Here are my hands and the sins that I have committed with them against myself. O Most-Great Being, whose assistance is hoped for every great difficulty, O Great Being, forgive the major sins. My face has prostrated to the One Who created it and fashioned its ears and eyes.
اللَّهُمَّ ارْزُقْنِي قَلْبًا تَقِيًّا، مِنَ الشَّرِّ نَقِيًّا، لَا جَافِيًا وَلَا شَقِيًّا
O Allah! Bless me with a pious heart, clean from sin, neither hard nor wretched.
