Do not allow your heart to take pleasure with the praises of people, nor be saddened by their condemnation.
You must convince your heart that whatever Allah has decreed is most appropriate and most beneficial for you.
Dear friend, Your heart is a polished mirror. You must wipe it dean of the veil of dust that has gathered upon it, because it is destined to reflect the light of divine secrets.
When you have a bad suspicion about a Muslim in your heart, you should increase your consideration toward him and make dua for him. This way you will infuriate Satan and will be able to drive him away. Because of this, Satan will be reluctant to put evil thoughts into your heart, afraid that you would increase your consideration towards your brother and will make dua for him again.
Remember it is the heart and not the body, which strives to draw near to God. By heart I do not mean the flesh perceived by the senses, but that secret thing which is sometimes expressed by spirit, and sometimes by soul.
