Hadith #3

3ـ ابْنُ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنِ الرَّجُلِ يَطُوفُ بَيْنَ الصَّفَا وَالْمَرْوَةِ أَ يَسْتَرِيحُ قَالَ نَعَمْ إِنْ شَاءَ جَلَسَ عَلَى الصَّفَا وَالْمَرْوَةِ وَبَيْنَهُمَا فَيَجْلِسُ.

3. Ibn abu ‘Umayr has narrated from Hammad from al-Halabiy who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about a man who performs Sa‘y between al-Safa’ and al-Marwah: if he can rest. He (the Imam) said, ‘Yes, he can do so on al-Safa’ or al-Marwah or in between.’”
