مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ اَلْبَرْقِيِّ عَنْ سَعْدِ بْنِ سَعْدٍ عَنْ صَفْوَانَ قَالَ: سَأَلْتُ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ عَنْ رَجُلٍ اِحْتَاجَ إِلَى اَلْوُضُوءِ لِلصَّلاَةِ وَهُوَ لاَ يَقْدِرُ عَلَى اَلْمَاءِ فَوَجَدَ قَدْرَ مَا يَتَوَضَّأُ بِهِ بِمِائَةِ دِرْهَمٍ أَوْ بِأَلْفِ دِرْهَمٍ وَ هُوَ وَاجِدٌ لَهَا يَشْتَرِي وَ يَتَوَضَّأُ أَوْ يَتَيَمَّمُ قَالَ« لاَ بَلْ يَشْتَرِي قَدْ أَصَابَنِي مِثْلُ هَذَا فَاشْتَرَيْتُ وَ تَوَضَّأْتُ وَ مَا يُشْتَرَى بِذَلِكَ مَالٌ كَثِيرٌ».
Muhammad ibn Yahya, from Ahmad ibn Muhammad, from Al-Barqi, from Sa’d ibn Sa’d, from Safwan, who said:
I asked Abu Al-Hasan عليه السلام about a man who needed to perform wudu (ablution) for prayer but could not find water, except for an amount sufficient for wudu, priced at one hundred dirhams or even one thousand dirhams, and he had the means to purchase it. Should he buy it and perform wudu, or should he perform tayammum (dry ablution)? Imam عليه السلام said: "No, rather he should buy it. A similar situation happened to me, and I bought it and performed wudu. That amount of money is not considered a great loss."
