Hadith 666
من صلى فى مسجدى أربعين صلاة لا يفوته صلاة كتبت له براءة من النار ونجاة من العذاب وبرئ من النفاق
"Whoever performs forty prayers consecutively in my mosque, without missing any prayer, will have written for him freedom from the Fire, salvation from punishment, and freedom from hypocrisy."
