Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) once mentioned:
Why do we not find the time to regularly engage in zikr and ‘ibaadah, whereas it is these actions that will truly benefit us after our death? We are all aware that our life in this world is extremely short and can be likened to a dream. When a person has a dream, he sees many things, yet upon awakening, he finds that everything has disappeared and he realises that what he saw was nothing but a dream. Similarly, when a person passes away, he finds that everything of the world has disappeared and only good actions remain. Hence, if righteous actions are not carried out during one’s lifetime, the life after death will be nothing but misery and destruction. (Suhbat Baa Awliyaa pg. 205)
