The great spiritual master Dhu’n Nun al-Masri (Allah have mercy on him) said:

“The early Muslims (salaf) would counsel each other with three counsels:

First: Whoever rectifies their relationship with Allah, Allah rectifies their relationships with people.

Second: Whoever rectifies their inward, Allah rectifies their outward.

Third: Whoever rectifies their Hereafter, Allah rectifies their worldly life.”

[Sharh al-Hikam al-Ghawthiyya, 111]
