Arabic (Original)
قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ حَدَّثَنَا لَيْثٌ عَنْ عَبْدِ اللَّهِ بْنِ الْحَسَنِ عَنْ فَاطِمَةَ بِنْتِ حُسَيْنٍ عَنْ جَدَّتِهَا فَاطِمَةَ بِنْتِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَتْ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا دَخَلَ الْمَسْجِدَ قَالَ بِسْمِ اللَّهِ وَالسَّلَامُ عَلَى رَسُولِ اللَّهِ اللَّهُمَّ اغْفِرْ لِي ذُنُوبِي وَافْتَحْ لِي أَبْوَابَ رَحْمَتِكَ وَإِذَا خَرَجَ قَالَ بِسْمِ اللَّهِ وَالسَّلَامُ عَلَى رَسُولِ اللَّهِ اللَّهُمَّ اغْفِرْ لِي ذُنُوبِي وَافْتَحْ لِي أَبْوَابَ فَضْلِكَ.

He said: Abu Mu'awiyah told us: Layth told us, from Abdullah ibn al-Hasan, from Fatimah bint Husayn, from her grandmother Fatimah, daughter of the Messenger of Allah, peace and blessings be upon him, who said: The Messenger of Allah, peace and blessings be upon him, when he entered the mosque, would say: In the name of Allah, and peace be upon the Messenger of Allah. O Allah, forgive me my sins and open for me the gates of Your mercy; and when he left, he would say: In the name of Allah, and peace be upon the Messenger of Allah. O Allah, forgive me my sins and open for me the gates of Your bounty.
