Question: Is there any reward for [breaking the fast with] these preferable [food items]?
Response: One who does so in following the Prophet’s (sal-Allaahu ‘alayhi wa sallam) example, then for him is the reward of following him. Even if it is in the (simply mundane) acceptable (mubaah) matters (i.e. where there is no reward nor any sin attached to the action), if he were to follow (him) in these, then he would be rewarded for that action. Because of this, the scholars say: ‘Certainly with good intention, good habits become acts of worship’.
