Kamar yadda mutum zai iya kamuwa da cututtukan zuciya, haka ma yana iya kamuwa da cututtukan hankali. Amma a tunanin Musulunci, zuciya da hankali suna da alaƙa mai ƙarfi, ba za a iya raba su ba, har ta kai suna da tasiri kai tsaye a kan juna.

Just as one can suffer from diseases of the heart, so too can one suffer from diseases of the intellect. But in Islamic thought the heart and the intellect are intimately linked and inseparable such that they have a direct impact on each other.

Misali, girman kai yawanci ana fahimtarsa a matsayin cuta ta zuciya, amma girman kai yana shafar hankali kuma, wato ikon fahimta da kama gaskiya. Girman kai ma yana iya shafar idanu, har mutum ya makanta daga gaskiyar da take gaban idanunsa. Wannan kuwa abu ne da ake gani a kullum tare da mutanen da ke kewaye da mu, inda muke mamaki don me wasu ba sa iya ganin wani abu da yake bayyane haka. Haka ma ga cututtuka irin su hassada, ƙiyayya mai muni, da kwaɗayi. Irin waɗannan cututtuka suna da tsanani har ba sa lalata rai kawai, har ma suna kamuwa da dukan jiki, har zuwa matakin da suke ɓata ikon mutum na yin tunani a fili. Idan ka yi nazarin aikin wasu masu gyara a cikin Musulunci, za ka ga alamomin waɗannan cututtuka a cikin hujjojin da suke bayarwa da kuma matsayar da suke cimmawa. Allah Ya kiyaye mu daga irin wannan hali.
