The believer should be keen to utilize his time in the best possible way and not waste it. Many women spend hours after hours in preparing various kinds of foods in Ramadan.
A believer must not consume food inappropriately and should reduce his food intake. His main concern should not be to enjoy whatever he desires of food even if it is permissible and there is nothing wrong in eating food but he must not eat excessively.
'Umar ibn al-Khattaab entered upon his son 'Abd-Allaah and found him eating meat, and said, "What is this meat?" He said: "I fancied it." 'Umar said: "Every time you fancy something, you eat it?! It is enough extravagance for a man that he eats whatever he fancies!" May Allaah be pleased with them. The Muslim should limit himself to what he needs of food, and not go beyond that.
A Muslimah should serve her family but she must take care of her obligatory duties first. The time that she spends on these preparing fancy meals can be used in remembering Allah or reciting Quraan in Ramadan while she works.
It should also be noted that if her intention when preparing food is sound, namely to serve her husband and children, then that is an act of worship for which she will be rewarded.
A woman's work in her house is an act of worship to Allah and her taking care of her family and children, fulfilling their needs and maintaining the household etc are a form of worship and while she does that she is in state of worship. So she should make the most of the time in order to remember Allaah; it is permissible to remember Allaah whilst preparing food, praise be to Allaah.
Women should be moderate in all things and not go for extravagance. They must not forget to perform obligatory acts of worship just to cook something special.
May Allah protect us.
Sisters, know your priorities.
