“The Messenger of Allah (ṣ) said, ‘Be ashamed in front of Allah with true shame.’ Someone asked, ‘O Messenger of Allah, who is [considered to be] ashamed in front of Allah with true shame [and how can this be achieved]?’ He (ṣ) said, ‘Whoever wants to be ashamed in front of Allah with true shame, let him always keep his death before his eyes, be abstemious in this world and [uninterested in] its embellishments, protect the head and all that it perceives [of sight, sound, taste, and thought] as well as the stomach and all that it digests [from that which is forbidden], and [let him] never forget the graves and the decrepit ruins [which show that this world is evanescent].’”
