The Source of Traditions on Imam al-Riḍā (Vol 1) · Hadith 228 (#Ḥadīth #20)

20 - حَدَّثَنا أَبي وَمُحَمَّدِ بْنِ الحَسَن بْنِ أَحْمَدِ بْنِ الوَلِيد رَضِىَ اللهُ عَنْهُما قالَ: حَدَّثَنا مُحَمَّدِ بْنِ يَحْيَى العطار وَأَحْمَدِ بْنِ إِدْرِيس جَمِيعاً، عَن مُحَمَّدِ بْنِ أَحْمَدِ بْنِ يَحْيَى بْنِ عِمْران الأَشْعَرِيِّ قالَ أَحْمَدِ بْنِ مُحَمَّد بن خالِد، عَن أَبيهِ عَنْ بَكْرِ بْنِ صالِح، عَن الجَعْفَرِيِّ قالَ: سَمِعتُ أَبَا الْحَسَنِ a.sُ يَقُولُ قَلِّمُوا أَظْفَارَكُمْ يَوْمَ الثَّلاثَاءِ وَاسْتَحِمُّوا يَوْمَ الأَرْبِعَاءِ وَأَصِيبُوا مِنَ الْحَجَّامِ حَاجَتَكُمْ يَوْمَ الْخَمِيسِ وَتَطَيَّبُوا بِأَطْيَبِ طِيبِكُمْ يَوْمَ الْجُمُعَةِ

28-20 My father and Muhammad ibn Al-Hassan ibn Ahmad ibn al-Waleed - may God be pleased with them - narrated that Muhammad ibn Yahya al-Attar and Ahmad ibn Idris quoted on the authority of Muhammad ibn Ahmad ibn Yahya ibn Imran al-Ash’ari, on the authority of Ahmad ibn Muhammad ibn Khalid, on the authority of his father, on the authority of Bakr ibn Salih, on the authority of Al-Ja’fari that he had heard Abul Hassan Al-Ridha (s) say, “Cut your nails short on Tuesdays. Take a bath on Wednesdays. Go to perform blood-letting on Thursdays and put on your best perfumes on Fridays.”
