Three attributes that are signs of suspicion of God

Imam Ali (as) says:

Even though miserliness, cowardice and greed are different qualities, yet they are all caused by suspecting Allah .

إنَّ البُخْلَ وَالجُبْنَ وَالحِرْصَ غَرَائِزُ شَتَّی یَجْمَعُهَا سُوءُ الظَّنِّ بِاللهِ.

Nahj al-Balaghah, letter 53.
