عَنْ أُسَامَةَ بْنِ زَيْدٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: قَدْ جَمَعَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ بِالْمُزْدَلِفَةِ (زَادَ فِي رِوَايَةٍ: وَلَمْ يُصَلِّ بَيْنَهُمَا شَيْئًا)
It is narrated from Sayyiduna Usama bin Zaid (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) combined the Maghrib and Isha prayers at Muzdalifah and did not perform any voluntary prayer between them.
