indeed safa and marwah are among allahs sacraments. so whoever makes hajj to the house or performs the umrah there is no sin upon him to circuit between them. should anyone do good of his own accord then allah is indeed appreciative allknowing.
إن الصفا والمروة من شعائر الله فمن حج البيت أو اعتمر فلا جناح عليه أن يطوف بهما ومن تطوع خيرا فإن الله شاكر عليم
