Q 2:
Should a person, who is invited by a Muslim brother to a daytime meal, break Sawm (Fast)?
A:
It is not permissible to break an obligatory Sawm. As for voluntary Sawm, a Muslim has the choice either to continue or break the Sawm, although it is better to continue Sawm. It is authentically reported that the Prophet (peace be upon him) said:
When any of you is invited to a meal, they should accept (the invitation). If they are fasting, they should say, 'I am fasting.'
In another wording, the Prophet (peace be upon him) is reported to have said:
If they are fasting, they should make Du`a' (for the inviter), and if they are not fasting, they should partake of the meal.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
