1.
My son, when you pray, do it like a person who is bidding farewell to this world, and don't assume you will have another chance to pray again. My son, know that a believer dies in between two deeds, one he offers for today, where he will get immediate blessings, and the second deed is what he offers towards the day of resurrection, and that is where he will gain the ultimate benefits
