7ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ هِشَامِ بْنِ سَالِمٍ قَالَ
أَرْسَلْنَا إِلَى أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) وَنَحْنُ جَمَاعَةٌ وَنَحْنُ بِالْمَدِينَةِ إِنَّا نُرِيدُ أَنْ نُوَدِّعَكَ فَأَرْسَلَ إِلَيْنَا أَنِ اغْتَسِلُوا بِالْمَدِينَةِ فَإِنِّي أَخَافُ أَنْ يَعْسُرَ عَلَيْكُمُ الْمَاءُ بِذِي الْحُلَيْفَةِ فَاغْتَسِلُوا بِالْمَدِينَةِ وَالْبَسُوا ثِيَابَكُمُ الَّتِي تُحْرِمُونَ فِيهَا ثُمَّ تَعَالَوْا فُرَادَى أَوْ مَثَانِيَ.
7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ibn Abi ‘Umayr from Hisham ibn Salim who has said the following: “We were in a group in al-Madinah and we sent someone to abu ‘Abd Allah 
, to ask for permission to visit him (the Imam) and say farewell. He (the Imam) sent back a message saying,
‘Take Ghusl (bath) in al-Madinah; I am afraid you may face difficulties to find water in Dhul Hulayfah, so take Ghusl (bath) in al-Madinah, wear your cloth of Ihram, then come to me one by one or two people at a time.’”
