عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ لِيَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَا عَلِيُّ أَسْبِغِ الْوُضُوءَ وَإِنْ شَقَّ عَلَيْكَ وَلَا تَأْكُلِ الصَّدَقَةَ وَلَا تُنْزِ الْحَمِيرَ عَلَى الْخَيْلِ وَلَا تُجَالِسْ أَصْحَابَ النُّجُومِ
It is narrated from Sayyiduna Ali (may Allah be pleased with him), he says: The Noble Prophet (peace and blessings be upon him and his family) said to me: O Ali! Perform ablution completely, even if it feels burdensome to you, do not eat charity, do not make a donkey mount a mare, and do not sit in the gathering of astrologers.
