Be merciful to the sick and give thanks to God for the health."

Beware the excesses of the world, for the excesses of the world are an abomination in God's eyes."

Jesus said to John, "...Do not stare at what does not belong to you, for what you have not seen will not make you wiser and what you do not hear will not trouble you."

"Which man offers sincere counsel for the sake of God?" they asked. "He who begin by fulfilling his duties toward God before his duties of men. When faced with two choices, worldly matters and matters of the afterlife, he begins with what concerns the afterlife and then turns his attention to this world."

God revealed to Jesus: "O Jesus, I have granted you the love of the poor and mercy toward them. You love them, and they love you and accept you as their spiritual guide and leader, and you accept them as companions and followers. These are two traits of character. Know that whoever meets me on Judgment Day with these two character traits has met with the purest of works and the ones most beloved by me." 
Jesus used to say, "Truly I say to you, to eat wheat bread, to drink pure water, and to sleep upon dunghills with the dogs more than suffices him who wishes to inherit paradise." 
Jesus said, "It is no use to you to come to know what did you know, so long as you do not act in accordance with what you already know. Too much knowledge only increase pride if you do not act in accordance with it.' 
Jesus said, "Time revolves around three days: a yesterday which has passed away and during which you had been admonished, a today which supplies your needs, and a tomorrow in which you do not know what is in store for you. All matters revolve around three things: a thing which you must follow, a thing whose evil has become apparent to you and which you must shun, and a thing which appears uncertain to you and which you must defer to God."
