"I heard Abu Humaid and Abu Usaid say: 'The Messenger of Allah ﷺ said: "When any one of you enters the Masjid, let him say: 'Allahumma aftahli abwaba rahmatik (O Allah, open to me the gates of your mercy). And when he leaves let him say: Allahumma inni as'aluka min fadlik (O Allah, I ask You of Your bounty).'"  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا دَخَلَ أَحَدُكُمُ الْمَسْجِدَ فَلْيَقُلِ اللَّهُمَّ افْتَحْ لِي أَبْوَابَ رَحْمَتِكَ وَإِذَا خَرَجَ فَلْيَقُلِ اللَّهُمَّ إِنِّي أَسْأَلُكَ مِنْ فَضْلِكَ  

"When Messenger of Allah entered the Masjid he said Salat and Salam upon Muhammad and then said: (Rabbighfirli dhunubi, waftahli abwaba rahmatik) 'O pardon my sins, and open the gates of Your mercy for me.' And when he exited he said Salat and Salam upon Muhammad, and then said: (Rabbighfirli dunubi, waftahli abwaba rakmatik) 'O Lord pardon my sins, and open the gates of Your blessings for me.'"  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا دَخَلَ الْمَسْجِدَ صَلَّى عَلَى مُحَمَّدٍ وَسَلَّمَ وَقَالَ رَبِّ اغْفِرْ لِي ذُنُوبِي وَافْتَحْ لِي أَبْوَابَ رَحْمَتِكَ وَإِذَا خَرَجَ صَلَّى عَلَى مُحَمَّدٍ وَسَلَّمَ وَقَالَ رَبِّ اغْفِرْ لِي ذُنُوبِي وَافْتَحْ لِي أَبْوَابَ فَضْلِكَ  

"Whenever the Messenger of Allah entered the mosque he would say: 'Bismillah, was-salamu 'ala Rasulillah, Allahummagh-firli dhunubi waftah li abwaba rahmatika. (In the Name of Allah, and peace be upon the Messenger of Allah. O Allah, forgive me my sins and open to me the gates of Your mercy).' When he left he would say: 'Bismillah, was-salamu 'ala Rasulillah, Allahummagh-firli dhunubi waftah li abwaba fadlika. (In the Name of Allah, and peace be upon the Messenger of Allah. O Allah, forgive me my sins and open to me the gates of Your bounty).'"
