172 - قَالَ أَبُو جَعْفَرٍ اَلْبَاقِرُ عَلَيْهِ اَلسَّلاَمُ: «اَلْغُسْلُ فِي سَبْعَةَ عَشَرَ مَوْطِناً لَيْلَةِ سَبْعَ عَشْرَةَ مِنْ شَهْرِ رَمَضَانَ وَ لَيْلَةِ تِسْعَ عَشْرَةَ وَ لَيْلَةِ إِحْدَى وَ عِشْرِينَ وَ لَيْلَةِ ثَلاَثٍ وَ عِشْرِينَ وَ فِيهَا يُرْجَى لَيْلَةُ اَلْقَدْرِ وَ غُسْلُ اَلْعِيدَيْنِ وَ إِذَا دَخَلْتَ اَلْحَرَمَيْنِ وَ يَوْمِ تُحْرِمُ وَ يَوْمِ اَلزِّيَارَةِ وَ يَوْمِ تَدْخُلُ اَلْبَيْتَ وَ يَوْمِ اَلتَّرْوِيَةِ وَ يَوْمِ عَرَفَةَ وَ إِذَا غَسَّلْتَ مَيِّتاً وَ كَفَّنْتَهُ أَوْ مَسِسْتَهُ بَعْدَ مَا يَبْرُدُ وَ يَوْمِ اَلْجُمُعَةِ وَ غُسْلُ اَلْكُسُوفِ إِذَا اِحْتَرَقَ اَلْقُرْصُ كُلُّهُ فَاسْتَيْقَظْتَ وَ لَمْ تُصَلِّ فَعَلَيْكَ أَنْ تَغْتَسِلَ وَ تَقْضِيَ اَلصَّلاَةَ وَ غُسْلُ اَلْجَنَابَةِ فَرِيضَةٌ.
Hadith.172 - Imam Muhammad ibn Ali Al-Baqir 
said:
'There are seventeen occasions for ghusl (ritual bathing): on the night of the 17th of the month of Ramadan, the night of the 19th, the night of the 21st, and the night of the 23rd—on which Laylat al-Qadr (the Night of Decree) is hoped for. Also, ghusl on the two Eid’s (Eid al-Fitr and Eid al-Adha), upon entering the two holy sanctuaries (Mecca and Medina), on the day of putting on the ihram (for pilgrimage), the day of visiting (the sacred sites), the day of entering the House (the Kaaba), the day of Tarwiyah (the 8th of Dhu al-Hijjah), the day of Arafah (the 9th of Dhu al-Hijjah), after washing a deceased person and shrouding them, or if you touch the deceased after their body has cooled.
There is also ghusl for Jumu’ah, for a solar eclipse if the entire disc of the sun is obscured, and if you wake up and have not prayed, then you must perform ghusl and make up the prayer. Ghusl for janabah (ritual impurity from sexual discharge) is obligatory.'"
