Is breaking the fast at the mosque with the congregation more important than breaking the fast at home with a tired, pregnant wife?

Part of treating one's wife kindly (al-mu'asharah bi al-ma'ruf) is for the husband to fulfill his wife's needs concerning her religious and worldly affairs. This includes teaching her about her religion and creed, being with her when she needs him, comforting her, and treating her well, especially at the beginning of married life and during pregnancy. The Prophet, peace and blessings be upon him, used to serve his family. The husband's statement that his actions are dictated by Islamic teachings is incorrect; rather, a husband serving and caring for his family has a great reward. The Prophet, peace and blessings upon him, said: "Begin with those whom you support." This does not mean that he must break his fast with his wife every day, but kindness towards her and the household is required.
