Hakeemul Ummah Hazrat Moulana Ashraf Ali Thaanwi Sahib رحمه الله has said that having a lack of order and being negligent in cleanliness is harmful not only in worldly matters but impacts negatively on one’s Deeni affairs. A lack of system in one’s routine affairs is detrimental for even one’s baatini (spiritual and moral) issues.
