Sufyaan Ibn ‘Uyaynah said:
If [one’s] deeds done in secret are equal to [one’s] deeds done in public, then that is fair.
And if [one’s] deeds done in secret are better than [one’s] deeds done in public, then that is better.
And if [one’s] deeds done in public are better than [one’s] deeds done in secret, then that is unjust.
