Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) once mentioned:

The nature of many people is such that it very quickly inclines towards despondency and despair. The reason is that once a person loses hope and becomes despondent; he regards himself to be free from all responsibilities and therefore neglects his obligations. Remember that causing one to lose hope and become despondent is one of the main traps of the nafs and Shaitaan. (Malfoozaat Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) pg. 80)
