In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Ibn Abbaas [may Allaah be pleased with him and his father] said that the Prophet [peace and blessings of Allaah be upon him] said, “There are two blessings that many people are deceived into losing: health and free time.” [Sahih al-Bukhari 6412]
Al-Hasan Al-Basri [may Allaah have mercy upon him] said, :”I met a people who were more eager to guard their time than than dirhams and dinars (i.e. money)”. [Saydul Khaatir 241]
Imaam Ibnul Jawzee [may Allaah have mercy upon him] said: Indeed, I have witnessed (the affair) of many people- those who are unaware of the [real] meaning of life. Amongst them is one who has no need of seeking after a livelihood due to his abundant wealth, but he sits in the market most of the day staring at the people, and how many offensive [things] and evil deeds go past him! Amongst them is one devoted to playing chess, others pass time by talking about the rulers and others talk about the high and low prices of [goods and services]. So I knew that Allaah [The Most High] has not given everyone the blessing to realize the nobility of [one’s] life span and acquaintance with the value of [one’s] period of well-being, except to the one whom it is bestowed and blessed with the zeal to profit from that. [An Excerpt from Saydul Khaatir: page:241]
Imaam Ibnul Jawzi [may Allaah have mercy upon him] said: It is befitting a person that he should know the worth of his era and the value of his time, so that he does not waste a moment of it in anything other than seeking to earn the pleasure and reward of Allaah, and give precedence to the best of word and deeds. And that his intention what what is good be established without apathy in what the body is not incapable of doing”. [Saydul Khaatir. page 34]
Sulaymaan Ad-Daaraanee [may Allaah have mercy upon him] said: If the sane (sensible) person did not weep during the rest of his life except due to the pleasure of what he missed from obedience to Allaah, then he should weep until his time of death arrives”. [Hilyatul Aliyaa 9/275]
Ibn Aqeel [may Allaah have mercy upon him]: It is not permissible for me to waste an hour of my life, even if my tongue is unable to engage in study and discussion, and my eyes are unable to read. I engage with my thoughts in my time relaxation while lying down, so that I do not get up except that have something to write. [Dhayl Tabaqaat Al-Hanaabilah 1/145]
Imaam Ibnul Qayyim [may Allaah have mercy upon him] said: “Wasting time is worse than death, because wasting time cuts you off from Allaah and the Hereafter, whilst death cuts you off from the world and its people”. [Al-Fawaa’id. page 44]
Imaam Ibnul Qayyim [may Allaah have mercy upon him] said: Every breath of life is a precious gem that has no portion of (doing something good), it could buy a treasure of treasures whose bliss will never end. Wasting these breaths, or its owner buying by way of it what brings his destruction is a great loss that only the most ignorant, foolish and least sensible people allow to occur, because indeed the reality of this loss will be clear to him on the Day of Mutual Loss and Gain [i.e. the Day of Judgement].
يَوْمَ تَجِدُ كُلُّ نَفْسٍ مَا عَمِلَتْ مِنْ خَيْرٍ مُحْضَراً وَمَا عَمِلَتْ مِن سُوءٍ تَوَدُّ لَوْ أَنّ بَيْنَهَا وَبَيْنَهُ أَمَداً بَعِيداً
On the Day when every person will be confronted with all the good he has done, and all the evil he has done, he will wish that there were a great distance between him and his evil. [Surah Aal Imraam. Verse 30] [Ighaatha Al-Lahfaan. page 89]
Imaam Ibnul Jawzi [may Allaah have mercy upon him] said, “O you whose breaths are assigned a limit and whose deeds are observed! Would you spend your precious life in the pursuit of vile desires?!” [Al-Mudhish page 553]
