surely the safa and the marwa are among the signs appointed by allah so whoever makes a pilgrimage to the house or pays a visit there is no blame on him if he goes round them both and whoever does good spontaneously then surely allah is grateful knowing.
إن الصفا والمروة من شعائر الله فمن حج البيت أو اعتمر فلا جناح عليه أن يطوف بهما ومن تطوع خيرا فإن الله شاكر عليم
