Jesus, peace be upon him, said:

Do not, like lords, look upon the faults of others. Rather, like servants, look after your own faults. In truth, humanity is comprised of only two types of people: the afflicted and the sound. So show mercy to the afflicted, and praise God for well-being.

from al-Muwatta’ of Imam Malik (d. 179/795)
