The word(s) "harsh-hearted" appears 1 time(s) in 1 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) It is part of the Mercy of Allah that thou dost deal gently with them Wert thou severe or harsh-hearted, they would have broken away from about thee: so pass over (Their faults), and ask for (Allah's) forgiveness for them; and consult them in affairs (of moment). Then, when thou hast Taken a decision put thy trust in Allah. For Allah loves those who put their trust (in Him).
