Internal Characteristics
“Just as donning an ‘amāmah (turban) and using a siwāk are beloved sunnah practices of the Prophet sallallahu alyhi wasallam, adorning one’s heart with praiseworthy characteristics is also sunnah.
Modesty, humbleness and keeping oneself free from spiritual maladies such as pride, greed and vanity are also sunnah practices of the Prophet sallallahu alyhi wasallam that need to be adopted in order to become a complete believer.”
