‘Abdallah b. Mughaffal reported God’s Messenger as saying, “Between every pair of <i>adhans</i> there is a prayer; between every pair of <i>adhans</i> there is a prayer.” Then he said on repeating it a third time, “for him who wishes.” (Bukhari and Muslim.)

وَعَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «بَيْنَ كُلِّ أَذَانَيْنِ صَلَاةٌ بَيْنَ كُلِّ أَذَانَيْنِ صَلَاةٌ» ثُمَّ قَالَ فِي الثَّالِثَةِ «لِمَنْ شَاءَ»
