٤ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ هِشَامِ بْنِ سَالِمٍ عَنْ حَكَمِ بْنِ حُكَيْمٍ الصَّيْرَفِيِّ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) أَبُولُ فَلاَ أُصِيبُ الْمَاءَ وَقَدْ أَصَابَ يَدِي شَيْ‏ءٌ مِنَ الْبَوْلِ فَأَمْسَحُهُ بِالْحَائِطِ أَوِ التُّرَابِ ثُمَّ تَعْرَقُ يَدِي فَأَمْسَحُ وَجْهِي أَوْ بَعْضَ جَسَدِي أَوْ يُصِيبُ ثَوْبِي قَالَ لاَ بَأْسَ بِهِ.
4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hisham ibn Salim from Hakam ibn Hukaym al-Sayrafiy who has said the following: “I once said to abu ‘Abd Allah , ‘I may urinate but do not find water, my hands have come in contact with urine and I wipe it against the wall or soil. Then it perspires and I wipe my face with it or other parts of my body or my clothes. He (the Imam) said, ‘It is not harmful.’”
