Imâm Ibn al Jawzi رحمه الله said:
Why is the sense of fearing Allah not growing?
Why do you seem to have no distress about the Hereafter?
Why do you seem to not have any sort of cautiousness regarding your final destination?
Have you not heard of the stories and news of the tireless endeavours and worship of the good worshippers of old times?
Did you not know that the Messenger of Allah (ﷺ) is the master of all beings but still he prayed all night until his feet were swelling?
Did you not know that Abu Bakr (رضي الله عنه) was known for his excessive weeping when praying?
Did you not know that ‘Umar Ibn al-Khattab (رضي الله عنه) had two dark lines on his cheek from the amount of tears he cried?
Did you not know that ‘Uthman Ibn ‘Affan (رضي الله عنه) used to recite the entire Qur’an in one unit of prayer?
Did you not know that ‘All (رضي الله عنه) used to weep at night while he was praying in his niche until his beard became all wet while saying, ‘O worldly life, you may tempt someone else but not me?’
Did you not know that al-Hasan al-Basrl lived all his life being worried about his Hereafter?
Did you not know that Sa‘d Ibn al-Musayyab was a patron in the Masjid and so he did not miss a congregational prayer (salah) in the masjid for forty years?
Did you not know that when the daughter of al-Rabi Ibn Khaytham asked her father: ‘Why do I see people sleep at night while you are still awake?’ He answered, “Your father fears the punishment of grave.“
Did you not know that Abu Muslim al-Khawlanl used to hang a whip on the wall of the Masjid to alert himself with it lest he felt lazy while praying?
Did you not know that though Yazid al-Ruqashi fasted forty years, he kept saying, ‘Woe to me, the worshippers are still ahead of me?’
Did you not know that al-Mansur Ibn al-Mu’tamir fasted for forty years?
Did you not know that Sufyan al-Thawri used to cry blood because of his fear of Allah?
Did you not know that Ibrahim Ibn Adham used to urinate blood because of his fear of Allah?
So, beware of occupying yourself with knowledge while neglecting acting upon it because this is indeed the state of those suffering permanent laziness.
