Hadith 1:67
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 } (73)
