"We used to look at Sufyan al-Thawri and you’d think he was drowning in a ship.
He’d always be saying, “O Allah, save us! O Allah save us!”
We are to bear in mind that time has certain characteristics, among of which are the following:
1-Time passes quickly.
2-Time that passes can never return, nor can it be compensated for, for time is irretrievable.
3-Time is the most precious thing that man possesses.
Imam Al-Hasan Al-Basri says: “At the beginning of every day a herald calls: ‘O son of Adam! I am a new creation and a witness of your deeds. So take a provision from me because when I pass, for I never come beck till the Day of Resurrection.’”
In another hadith, the Prophet, peace and blessings be upon him, said: “There are two of Allah’s favors that are forgotten by many people: health and free time.”
“The Qur’an and the Sunnah make it clear that time is very valuable. Almighty Allah says: “By the time! Verily man is in loss.” (Al-`Asr:1-2) The Sunnah of the Prophet, peace and blessings be upon him, is also a rich record of many Hadiths that acknowledge the value of time and confirm the responsibility of man on how he maintains it; he will be brought to account by Allah on the Day of Judgment. Mu`adh ibn Jabal quotes the Prophet, peace and blessings be upon him, as saying: “A servant of Allah will remain standing on the Day of Resurrection until he is asked about four things: his life and how he spent it, his youth and how he used it up, his property and how he acquired and managed it and his knowledge and how he utilized it.”
So beware of time and how you spend it…it will never stop for you, but it will be against you.
