Quotes and Status on Strong and Weak Faith: People of Certainty ( Yaqeen in Iman)

 Shaykh ul-Islām ibn Taymiyyah [may Allāh have mercy on him] said: 

“The people of certainty [yaqeen] when they are tested; they remain firm. Unlike others, whom when tested may permit it [the test] to follow the resignation of his faith or [to allow] it to diminish.’’
