“One of the advices of my father, may Allah’s peace be upon him, was: ‘O son! Trim your nails and moustache. Start trimming nails from the small finger of right hand and whenever you do the above two deeds, recite this supplication Bismillaahi wa billaahi wa a’laa millati rasoolillaah. O son! To one who performs this deed Allah would grant the reward of releasing a slave for each nail and hair trimmed and he will not be involved in any disease except death.”
