`Sayyiduna Ibn Abbas (may Allah be pleased with them both) says that` the Messenger of Allah (peace and blessings be upon him) sent me from Muzdalifah with the luggage (or he said: with the weak ones) during the night.
It is narrated from Salim bin Abdullah that (his father) Sayyiduna Abdullah bin Umar, may Allah be pleased with them both, used to send the weak people who were with him ahead so that they could spend the night at Al-Mash'ar Al-Haram, which is in Muzdalifah, and remember Allah as long as they wished. Then they would return before the Imam's standing. So some of them would reach Mina at the time of the morning prayer and some after it. And Sayyiduna Ibn Umar, may Allah be pleased with them both, used to say that the Messenger of Allah, peace and blessings be upon him, had permitted these weak people to do so.
