From him, from Fudayl ibn Uthman from Abdullah ibn al-Hasan who said: It was said: “When you enter the mosque, say: ‘O’ Allah سبحانه وتعالى, forgive me my sins and open for me the doors of Your mercy’. And when you leave, say: ‘O’ Allah سبحانه وتعالى, forgive me and open for me the doors of Your grace’.”
