Hadith 31-32

وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ‏ صَلَّى اللهُ عَلَيْهِ وَآلِهِ: إِنّا أَهْلُ بَيْتٍ لا تَحِلُّ لَنا الصَّدَقَةُ وَقَدْ أُمِرنا بِإِسباغِ الطَّهُورِ؛ وَأَن لا نَنزِي حِماراً عَلَى عَتِيقَةٍ.

According to the same documentation, God’s Prophet (S) said, “We - Members of the Holy Household - cannot accept charity. We are instructed to perform the ablutions with the full obligatory and recommendable procedures. We are also instructed not to force a good horse to copulate with a donkey. [12] ”
