Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaihi) once mentioned:
O my beloved friends! Remember death continuously! Continue pondering over the spectacle of death. At the time one departs from this world, he will leave behind all his belongings and he will leave empty handed. (Malfoozaat of Hazrat Shaikh pg. 153)
