Hadith #1

1ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ وَمُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ جَمِيعاً عَنْ حَمَّادِ بْنِ عِيسَى عَنْ حَرِيزٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ سَأَلْتُهُ عَنْ رَجُلٍ أَجْنَبَ فِي السَّفَرِ وَلَمْ يَجِدْ إِلاَّ الثَّلْجَ أَوْ مَاءً جَامِداً فَقَالَ هُوَ بِمَنْزِلَةِ الضَّرُورَةِ يَتَيَمَّمُ وَلاَ أَرَى أَنْ يَعُودَ إِلَى هَذِهِ الأرْضِ الَّتِي تُوبِقُ دِينَهُ.

1. Ali ibn Ibrahim has narrated from his father and Muhammad ibn Yahya from Ahmad ibn Muhammad all from Hammad ibn ‘Isa from Hariz from Muhammad ibn Muslim who has said the following: “I once asked abu ’Abd Allah, ‘Alayhi al-Salam, about a man who experiences sexual relation during a journey and cannot find anything other than snow or ice. He (the Imam) said, ’This is like an emergency case and he must take Tayammum. I do not consider it proper for him to return to such land which ruins his religion.’”
