Extravagance in offering iftaar – does it reduce the reward of fasting?
Question

Does going to extremes in preparing food for iftaar reduce the reward of fasting?.
Praise be to Allah.It does not reduce the reward of fasting. A haram action that is done after the fast ends does not reduce its reward, but that is included in the words of Allah (interpretation of the meaning): 
“and eat and drink but waste not by extravagance, certainly He (Allah) likes not Al‑Musrifoon (those who waste by extravagance)” [al-A’raaf 7:31]
Extravagance itself is forbidden, and moderation is essential. If they have more than they need, they should give it in charity, for that is better. End quote.
