4ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيْهِ السَّلاَم) الْغُسْلُ يَوْمَ عَرَفَةَ إِذَا زَالَتِ الشَّمْسُ وَتَجْمَعُ بَيْنَ الظُّهْرِ وَالْعَصْرِ بِأَذَانٍ وَإِقَامَتَيْنِ.
4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘The Ghusl (bath) on the day of ‘Arafah, is at Zawal (declining of the sun toward the west at noontime) and you must perform al-Zuhr and al-‘Asr Salat (prayer) together with one Adhan and two ‘Iqamah.’”
