Anas said, “When we were in Medina, the moment the <i>mu’adhdhin</i> made the call to the sunset prayer the people hastened to the pillars of the mosque and prayed two <i>rak'as</i>, with the result that any stranger coming into the mosque would think that the obligatory prayer had been observed owing to the number who were praying them.” Muslim transmitted it.

وَعَنْ أَنَسٍ قَالَ: كُنَّا بِالْمَدِينَةِ فَإِذَا أَذَّنَ الْمُؤَذِّنُ لِصَلَاةِ الْمَغْرِبِ ابْتَدَرُوا السَّوَارِيَ فَرَكَعُوا رَكْعَتَيْنِ حَتَّى إِنَّ الرَّجُلَ الْغَرِيبَ لَيَدْخُلُ الْمَسْجِدَ فَيَحْسَبُ أَنَّ الصَّلَاةَ قَدْ صُلِّيَتْ مِنْ كَثْرَةِ مَنْ يُصَلِّيهمَا. رَوَاهُ مُسلم
