nation of oppressors
Allah does not guide the nation of oppressors (alqawma alththalimeena). The building which they have built will never cease to be a source of deep disquiet in their hearts until their hearts are cut into pieces. And Allah is all-knowing, wise. (Qur’an 9:110)
in whose hearts was disease
…the hypocrites and those in whose hearts was disease were saying, “Their faith has deluded these [believers]!” But he who places his trust in Allah [knows that], verily, Allah is almighty, wise. (Qur’an 8:49)
respond to the call
O you who have attained to faith! Respond to the call of Allah and the Apostle whenever he calls you unto that which will give you life; and know that Allah intervenes between man and his heart, and that unto Him you shall be gathered. (Qur’an 8:24)
strengthen the heart
Hu caused inner calm (nu’as) to enfold you, as an assurance from Hu, and sent down upon you water from the skies, so that Hu might purify you thereby take away from you the pollution of shaytan and strengthen your hearts and thus make firm your steps. (Qur’an 8:11)
those whose hearts tremble
Momineen are only they whose hearts tremble with awe whenever Allah is mentioned, and whose faith is strengthened whenever His messages are conveyed unto them, and who in their Sustainer place their trust. (Qur’an 8:2)
gently
And it was by Allah’s grace that you [O Prophet] did deal gently with your followers: for if you had been harsh and hard of heart, they would indeed have broken away from you. (Qur’an 3:159)
