Since we are in a great month. i just want to remind u True Muslim brotherhood implies that you should pray for your brother and want for him what you would want for yourself, and this is the fourth duty. You should pray for him as you pray for yourself making no distinction at all between you and him. You should pray during his life and death that he may have all he might wish for himself, his family and his dependents.

"The supplication of a Muslim for his brother without his knowledge is an accepted supplication and will be rewarded by the presence of an angel at his side. Every time he Supplicates for his brother the angel will say: Amen and the same for you too", (Muslim).

so say something for the person who comment before u and pray for him, this is less what we can do to increase our 'ajr'.
