So O you Muslims! Strive in this blessed night with Salaah and Du’aa and making istighfaar and righteous actions, for verily it is an opportunity of a lifetime, and the opportunities do not remain.
Fasting is patience in obeying Allaah, patience in keeping away from the things forbidden by Allaah, and patience in bearing the decree of Allaah, hunger, thirst, physical and mental weakness.
Make use of this month, Know its value and Estimate its worth. Respect it and spend its time in acts of obedience and worship, for this opportunity will not last. Nothing remains except the living and eternal (Allaah). So you will not remain and neither this month nor its days will remain.
Innovations have spread so much that it is looked upon as being a Sunnah, and when a person from true Ahlus Sunnah talks about some authentic sunnah then he is looked upon as if he is the one introducing new matters in the religion.
With regards to fasting that is accompanied by sins, the fast is not invalidated by that, rather it is valid and the fasting person has fulfilled his obligation and does not have to make up the fast.
