Real happiness and peace can be found in submitting to the commands of the Creator and the Sustainer of this world. God has said in the Quran:

“Truly, in remembering God do hearts find rest.” (Quran 13:28 )

On the other hand, the one who turns away from the Quran will have a life of hardship in this world. God has said:

“But whoever turns away from the Quran, he will have a hard life, and We will raise him up blind on the Day of Judgment.” (Quran 20:124)

This may explain why some people commit suicide while they enjoy the material comfort money can buy. For example, look at Cat Stevens (now Yusuf Islam), formerly a famous pop singer who used to earn sometimes more than $150,000 a night. After he converted to Islam, he found true happiness and peace, which he had not found in material success.

Enviornment:

Narrated by Jabir ibn Abdullah (Radhiallaho anho):
Allah’s Messenger (sallAllaahu ‘alaihi wasallam) said: Never a Muslim plants a tree, but he has the reward of charity for him, for what is eaten out of that is charity; what is stolen out of that, what the beast eat out of that, what the birds eat out of that is charity for him. (In short) none incurs a loss to him but it becomes a charity on his part.

Narrated by AbuDharr(Radhiallaho anho):
Allah’s Messenger (sallAllaahu ‘alaihi wasallam) said: In the morning charity is due from every bone in the body of every one of you. Every utterance of Allah’s glorification is an act of charity. Every utterance of praise of Him is an act of charity, every utterance of profession of His Oneness is an act of charity, every utterance of profession of His Greatness is an act of charity, enjoining good is an act of charity, forbidding what is disreputable is an act of charity, and two rak’ahs which one prays in the forenoon will suffice.

anyone makes (his wife) wash and he washes himself on Friday, goes
out early (for Friday prayer), attends the sermon from the beginning,
walking, not riding, takes his seat near the imam, listens
attentively, and does not indulge in idle talk, he will get the
reward of a year’s fasting and praying at night for every step he
takes.

me; grant me victory over those who act wrongfully towards me; O
Allah, make me grateful to Thee, mindful of Thee, full of fear
towards Thee, devoted to Thy obedience, humble before Thee, or
penitent. My Lord, accept my repentance, wash away my sin, answer my supplication, clearly establish my evidence, guide my heart, make true my tongue and draw out malice in my breast.”

GOD BRINGS GRIEVING PARENTS TO PARADISE –

The Prophet Muhammad (peace be upon him) said: “No pair of Muslims will lose three (of their children) by death without God bringing them into Paradise by His great mercy.” He was asked if that applied if they lost two children, and he said it did. He was also asked if it applied if they lost one child, and he said it did. Then the Prophet said: “By Him in Whose hand my soul (resides), (even) the (aborted fetus) draws his mother to Paradise by his umbilical cord when she seeks her reward for him from God.”
