أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ ، حَدَّثَنَا سُلَيْمَانُ يَعْنِي : ابْنَ بِلَالٍ ، عَنْ رَبِيعَةَ ، عَنْ عَبْدِ الْمَلِكِ بْنِ سَعِيدٍ ، عَنْ أَبِي حُمَيْدٍ أَوْ أَبِي أُسَيْدٍ قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ :" إِذَا دَخَلَ أَحَدُكُمْ الْمَسْجِدَ، فَلْيَقُلْ : اللَّهُمَّ افْتَحْ لِي أَبْوَابَ رَحْمَتِكَ، وَإِذَا خَرَجَ، فَلْيَقُلْ : اللَّهُمَّ إِنِّي أَسْأَلُكَ مِنْ فَضْلِكَ "

Abdullah bin Maslamah told us, Sulayman told us, meaning: Ibn Bilal, on the authority of Rabi’ah, on the authority of Abdul Malik bin Saeed, on the authority of Abu Humayd or Abu Usayd said: The Messenger of God, may God bless him and grant him peace, said: “If one of you enters the mosque, let him say: O God, open the doors for me.” Your mercy, and when he leaves, let him say: Oh God, I ask you of your grace.”
