وَعَنْ مُعَاذٍ بْنِ زُهْرَةَ
قَالَ: إِنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا أَفْطَرَ قَالَ: «اللَّهُمَّ لَكَ صَمْتُ وَعَلَى رِزْقِكَ أَفْطَرْتُ»
Muadh ibn Zuhra told that when the Prophet (sallallahu alayhi wa sallam) broke his fast he said, “O God, for Thee I have fasted and with Thy provision I have broken my fast.”
