Hadith 395
Sayyiduna Anas bin Malik (may Allah be pleased with him) says: When the Prophet (peace and blessings of Allah be upon him) would break his fast, he would say: ﴿بِسْمِ اللّٰهِ اَللّٰهُمَّ لَكَ صُمْتُ وَعَلَى رِزْقِكَ أَفْطَرْتُ﴾ "O Allah! For Your pleasure I have fasted and with Your provision I have broken my fast."
