Qatada asked Anas which supplication the Messenger of Allah ﷺ used to make most often.He replied, "The supplication he made most often was, 'O Allah, our Lord, grant us good in this world and good in the hereafter, and protect us from the punishment of the Fire.'"Ziyad added that whenever Anas wanted to make a supplication, he would make this one, and whenever he wanted to include a supplication within another, he would include this one in it.
حدثنا مسدد حدثنا عبد الوارث ح و حدثنا زياد بن أيوب حدثنا إسمعيل المعنى
سأل قتادة أنسا أي دعوة كان يدعو بها رسول الله ﷺ أكثر قال كان أكثر دعوة يدعو بها اللهم ربنا آتنا في الدنيا حسنة وفي الآخرة حسنة وقنا عذاب النار وزاد زياد وكان أنس إذا أراد أن يدعو بدعوة دعا بها وإذا أراد أن يدعو بدعاء دعا بها فيها
