In their hearts is a disease; and Allah has increased their disease: And grievous is the penalty they (incur), because they are false (to themselves).
Mufti Taqi Usmani
In their hearts there is a malady, so Allah has made them grow in their malady; and for them there is a grievous punishment, because they have been lying.
Muhammad Marmaduke Pickthall
In their hearts is a disease, and Allah increaseth their disease. A painful doom is theirs because they lie.
Sahih International
In their hearts is disease, so Allah has increased their disease; and for them is a painful punishment because they [habitually] used to lie.
French
Il y a dans leurs coeurs une maladie (de doute et d'hypocrisie), et Allah laisse croître leur maladie. Ils auront un châtiment douloureux, pour avoir menti.
