“And not equal are the good deed and the bad. Repel [evil] by that [deed] which is better; and thereupon the one whom between you and him is enmity [will become] as though he was a devoted friend.
But none is granted it except those who are patient, and none is granted it except one having a great portion [of good].”
Long time ago, lived al-Imam al-Ghazali [died 505 Hijra / 1111 CE].
He came not only to develop ways for an empirical approach to physical experiments, but to an empirical approach to spiritual matters as well. Have you not heard that Sufis of the old tested for the veracity of a narration of a Prophet by trying its content?
Take as an example the following narration from the Prophet, peace be upon him:
“You are given victory by supporting the weak ones among you.”
This narration is technically sound.
Put it to practice and see how your life changes.
While this great teacher, was leading a class, a visitor kept disturbing the natural flow of the teachings between him and the students. The students were furious but held back out of respect for their honourable teacher. When the visitor left, they enquired: “Teacher, why didn’t you instruct us to force him to leave? ” His reply was: “He was teaching me patience!”
Al-Ghazali has it as a rule:
“Desire makes slaves out of kings and patience makes kings out of slaves!”
