Abdullah ibn Amr reported: I said, “O Messenger of Allah, who are the best people?” The Messenger of Allah, peace and blessings be upon him, said:

ذُو الْقَلْبِ الْمَخْمُومِ وَاللِّسَانِ الصَّدُوقِ

One with a heart swept clean and truthful in speech.

We said, “O Messenger of Allah, we know truthful in speech. What is a heart swept clean?” The Prophet said:

هُوَ التَّقِيُّ النَّقِيُّ لا إِثْمَ فِيهِ وَلا بَغْيَ وَلا حَسَدَ

One that is mindful of Allah and pure, in which there is no sin, nor aggression, nor envy.

We said, “Who shows a sign of it?” The Prophet said:

الَّذِي يَشْنَأُ الدُّنْيَا وَيُحِبُّ الآخِرَةَ

One who hates worldliness and loves the Hereafter.

They said, “And who shows a sign of it?” The Prophet said:

مُؤْمِنٌ فِي خُلُقٍ حَسَنٍ

A believer with good character.
