Reported by Muslim and At-Tirmidhi who added the following words to the supplication:

(Allahumma aj’alni minat-tawwabina waj’alni minAl-mutatahhirina) “Oh Allah! Include me among those who repent and those who keep themselves pure”.

وَاَلتِّرْمِذِيُّ, وَزَادَ: { اَللَّهُمَّ اِجْعَلْنِي مِنْ اَلتَّوَّابِينَ, وَاجْعَلْنِي مِنْ اَلْمُتَطَهِّرِينَ } [1]‏ .‏
