Bulugh al-Maram

Narrated ‘Aisha (rad): When the Prophet (ﷺ) came out of the privy, he used to say, “Ghufranaka (O Allah! Grant me Your forgiveness)”. [Reported by Al-Khamsa, Abu Hatim and Al-Hakim graded it Sahih (sound)].

وَعَنْهَا; { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-كَانَ إِذَا خَرَجَ مِنْ اَلْغَائِطِ قَالَ: "غُفْرَانَكَ" } أَخْرَجَهُ اَلْخَمْسَةُ.‏ وَصَحَّحَهُ أَبُو حَاتِمٍ, وَالْحَاكِم ُ 1‏ .‏
