Hadith 7878 - وَ قَدْ رُوِيَ: «أَنَّ اَلْوُضُوءَ حَدٌّ مِنْ حُدُودِ اَللَّهِ لِيَعْلَمَ اَللَّهُ مَنْ يُطِيعُهُ وَ مَنْ يَعْصِيهِ وَ أَنَّ اَلْمُؤْمِنَ لاَ يُنَجِّسُهُ شَيْءٌ وَ إِنَّمَا يَكْفِيهِ مِثْلُ اَلدَّهْنِ.
Hadith.78 - It has been narrated (by Imam Muhammad ibn Ali Al-Baqir (as) ) that:
"Ablution is a limit set by Allah (swt) so that He may know who obeys Him and who disobeys Him. And a believer is not made impure by anything ; rather, something like oil is sufficient for him”.
