The Book of Prayer
]وَعَنْ جَابِرٍ- رَضِيَ اَللَّهُ عَنْهُ- أَنَّ رَسُولَ اَللَّهِ - صلى الله عليه وسلم -قَالَ : { مَنْ قَالَ حِينَ يَسْمَعُ اَلنِّدَاءَ : اَللَّهُمَّ رَبَّ هَذِهِ اَلدَّعْوَةِ اَلتَّامَّةِ , وَالصَّلَاةِ اَلْقَائِمَةِ , آتِ مُحَمَّدًا اَلْوَسِيلَةَ وَالْفَضِيلَةَ , وَابْعَثْهُ مَقَامًا مَحْمُودًا اَلَّذِي وَعَدْتَهُ , حَلَّتْ لَهُ شَفَاعَتِي يَوْمَ اَلْقِيَامَةِ } أَخْرَجَهُ اَلْأَرْبَعَةُ . [1]
Narrated Jabir (RA): Allah's Messenger (ﷺ) said: "If anyone says when he hears the Adhan: 'O Allah! Lord of this perfect call and of the regular prayer which is going to be established! Kindly give Muhammad (ﷺ) the right of intercession and superiority, and send him (on the Day of Judgement) to the best and highest place in Paradise which You promised him', he will be assured of my intercession on the Day of Judgement." [Reported by al-Arba'ah].
