Imam Sadiq (a.s) said: “Whenever a man enters his house he should stamp the floor with his shoes and clear his throat to let everybody know he has come and he does not see something disgusting.”
وعنه (عليه السلام) قال
يسلم الرجل إذا دخل على أهله، وإذا دخل يضرب بنعليه ويتنحنح، يصنع ذلك حتى يؤذنهم أنه قد جاء حتى لا يرى شيئا يكرهه.
