وَعَنْ عُرْوَةَ بْنِ مُضَرِّسٍ رضى الله عنه
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«مَنْ شَهِدَ صَلَاتَنَا هَذِهِ (يَعْنِي: بِالْمُزْدَلِفَةِ) فَوَقَفَ مَعَنَا حَتَّى نَدْفَعَ، وَقَدْ وَقَفَ بِعَرَفَةَ قَبْلَ ذَلِكَ لَيْلاً أَوْ نَهَارًا، فَقَدْ تَمَّ حَجُّهُ وَقَضَى تَفَثَهُ»
“Anyone who offered this prayer -at al-Muzdalifah- along with us, and waited with us until we returned to Mina, and he stayed at Arafat (on the 9th) before that by night or day, he would have completed the prescribed duties of Hajj.” Related by the five Imams. At-Tirmidhi and Ibn Khuzaimah graded it as Sahih.
