From the chosen one

By Prophet Jesus A.S, son of Lady Mary:
"Do not speak much without mentioning Allah because you wil harden your hearts. A hard heart is far from Allah, but you do not know. Do not look at the wrong actions of people as if you were lords. Look to your wrong actions as if you were slaves. Some people are afflicted by wrong action and some people are protected from it. Be merciful to the people of affliction and praise Allah for His protection." (Muslim)

By Prophet Muhammad S.AW.
"Whoever wakes up and this world is his main concern, Allah will make him scattered and shattered, and he will feel a sense of panic and loss, and he will get nothing of this world except that which has already decreed for him. But whoever gets up and is mostly concern about the Hereafter, Allah will cause him to feel focused and content and will give him a feeling of being independent, and worldly gains will come to him willingly or unwillingly" (Al-Tirmidhi)
