"But to those who believe and do deeds of righteousness, He will give their (due) rewards,- and more, out of His bounty: But those who are disdainful and arrogant, He will punish with a grievous penalty; Nor will they find, besides God, any to protect or help them."
 

(Holy Qur'an (Yusufali) 4:173)

"Then give the Glad Tidings to the Believers, that they shall have from God a very great Bounty."
 

(Holy Qur'an (Yusufali) 33:47)

"But those will prosper who purify themselves, and glorify the name of their Guardian-Lord, and (lift their hearts) in prayer. Nay (behold), ye prefer the life of this world; But the Hereafter is better and more enduring."
 

(Holy Qur'an (Yusufali) 87:14 to 087:17)

"There is no punishment worse than the punishment of God and no reward better than His. Worldly things are better heard than seen and heavenly things are better seen than heard. But in this you must be satisfied with what you hear from the Holy Prophet (s.a.s.) about goodness and grandness of heavenly blessings and be contented with the news of hidden bounties, because you cannot see them when alive.
 
Remember it is better to have less in the world and more in the next than to have more in this world and less in heavens, because very few things here are really beneficial and many are ultimately harmful."
