قال رسول الله صلى الله عليه وسلم: (( من أتى هذا البيت فلم يرفث ولم يفسق رجع كما ولدته أمه )) رواه مسلم

Allah's Messenger ( May peace be upon him ) said: (( He who comes to this house ( Ka'bah ) ( with the intention of performing pilgrimage ), and neither spoke indecently nor did he act wickedly, would return ( free from sin ) as on the ( very first ) day his mother bore him).
