"The Messenger of Allah ﷺ said: 'Between each two Adhans [1] there is a prayer, between each two Adhans there is a prayer, between each two Adhans there is a prayer, for whoever wants to do it." [1]Meaning, between the Adhan and Iqamah. (Using translation from Nasāʾī 681)  

قَالَ رَسُولُ اللَّهِ ﷺ «بَيْنَ كُلِّ أَذَانَيْنِ صَلَاةٌ بَيْنَ كُلِّ أَذَانَيْنِ صَلَاةٌ بَيْنَ كُلِّ أَذَانَيْنِ صَلَاةٌ لِمَنْ شَاءَ»  

[Machine] "The muezzin used to call the prayer for Maghrib during the time of the Messenger of Allah ﷺ , and the companions of the Messenger of Allah ﷺ would gather at the door. They would line up until the Messenger of Allah ﷺ would come out, and they would be in that state." He said, and he did not stay for long.  

كَانَ «الْمُؤَذِّنُ يُؤَذِّنُ لِصَلَاةِ الْمَغْرِبِ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فَيَقُومُ لُبَابُ أَصْحَابِ رَسُولِ اللَّهِ ﷺ فَيَبْتَدِرُونَ السَّوَارِيَ حَتَّى يَخْرُجَ رَسُولُ اللَّهِ ﷺ وَهُمْ كَذَلِكَ» قَالَ وَقَلَّ مَا كَانَ يَلْبَثُ
