Jabir bin Abdullah reported,

The Messenger of Allah ﷺ said, "Whoever says when he hears the call to prayer, 'O Allah, Lord of this perfect call and the prayer about to be established, grant Muhammad the means and the excellence, and raise him to the praiseworthy station which You have promised him,' my intercession will be granted to him on the Day of Resurrection."

عن جابر بن عبد الله

أن رسول الله ﷺ قال: من قال حين يسمع النداء: اللهم رب هذه الدعوة التامة، والصلاة القائمة، آت محمدا الوسيلة والفضيلة، وابعثه مقاما محمودا الذي وعدته، حلت له شفاعتي يوم القيامة.
