“Hi brothers and sisters just like to know what if you pray and you miss prayers during the day and you just skip it and forget about? Like not praying the whole day of prayers? Many people do this? And think its fine because the day has gone and no point in praying! Please tell me what you think”
Narrated Anas: The Prophet said, “If anyone forgets a prayer he should pray that prayer when he remembers it. There is no expiation except to pray the same.” Then he recited: “Establish prayer for My (i.e. Allah’s) remembrance.” (20.14).
In Islam praying 5 times a day is very important, it is so important that it is a sin to intentionally miss any. If a person misses any prayer unintentionally, he will be forgiven but he should see to it that he performs the prayers that have been missed whenever he remembers. If the person has missed a large number of prayers, then he should try and make up for as much as he can.
Best is to always ask Allah for forgiveness.
An example of a method of how to make up for numerous missed prayers is given here.
