It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: The fasting person has two occasions of joy and happiness; when he breaks his fast, he is happy, and there will be another happiness in the Hereafter when he meets Allah.
