The Day of Dedication and Prayers

عَنْ أَبِي عَبْدِ اللٌّهِقَالَ: وَالْعَمَلُ فِيهِ يَعْدِلُ ثَمَانِينَ شَهْراً، وَ يَنْبَغِي أَنْ يُّكَـثِّرَ فِيهِ ذِكْرَ اللٌّهِ عَزَّ وَ جَلَّ، وَالصَّلَوٌةَ عَلى النَّبِيِّوَيُوَسِّعَ الرَّجُلُ فِيهِ عَلى عَيَالِهِ

It has been narrated from Abi 'Abdillah [Imam Ja'far ibn Muhammad as-Sadiq] (peace be upon him) that he said, “The worth of (good) actions performed on this day (18th of Dhul Hijjah) is equivalent to 80 months (of good deeds) and one is advised to frequently remember Allah, the Noble and Grand, and send prayers upon the Prophet (blessings of Allah be upon him and his family) and that a man be generous to his family (by presenting them with gifts).”

The Day of Seeing the Leader

عَنْ مَوْلاَنَا أَبِي ‏الْحَسَنِ عَلِيَّ بْنِ مُحَمَّدٍقَالَ لأََبِي إِسْحَاقٍ: وَ يَوْمُ الْغَدِيرِ فِيهِ أَقَامَ النَّبِيُّأَخَاهُ عَلِيًّا عَلَمًا لِلنَّاسِ وَ إِمَامًا مِنْ بَعْدِهِ. [قَالَ] قُلْتُ: صَدَّقْتَ جُعِلْتُ فِدَاكَ، لِذٌلِكَ قَصَدْتُ، أَشْهَدُ أَنَّكَ حُجَّةَ اللٌّهِ عَلى خَلْقِهِ

 
It has been narrated from our master, Abul Hasan 'Ali ibn Muhammad [al-Hadi] (peace be upon him) that he said to Abi Ishaq: “The Day of Ghadir is the day when the Prophet (blessings of Allah be upon him and his family) appointed his brother 'Ali as the flag (of guidance) for the people and the Imam after him.”  Abu Ishaq said, “You have spoken the truth, may I be sacrificed for you.  It is for this reason (alone) that I came to see you.  I bear witness that truly you are the proof of Allah over all of His creations.”

The Day of Praising Allah

عَنْ عَلِيِّ بْنِ مُوْسى الرِّضَا:مَنْ زَارَ فِيهِ مُؤْمِناً أَدْخَلَ‏ اللٌّهُ قَبْرَهُ سَبْعِينَ نُوراً وَ وُسِّعَ فِي قَبْرِهِ وَ يَزُورُ قَبْرَهُ كُلَّ يَوْمٍ سَبْعُونَ أَلْفَ مَلَكٍ وَيُبَشِّرُونَهُ بِالْجَنَّةِ

Imam 'Ali ibn Musa al-Ridha (peace be upon him) has said, “Allah will grant a person who visits a true believer on it (the Day of 'Eidul Ghadir) seventy types of Divine Light in his grave and will expand his grave.  Every day, 70,000 Angels will visit him in the grave and they will grant him the glad tidings of Paradise.”

The Day of Visiting and Doing Good

قَالَ الصَّادِق:ُيَنْبَغِي لَكُمْ أَنْ تَتَقَرَّبُوا إِلـى اللٌّهِ تَعَالـى بِالْبِرِّ وَالصَّوْمِ وَالصَّلوٌةِ وَ صِلَةِ الْرَحْمِ وَ صِلَةِ الإِخْوَانِ، فَاِنَّ الأَنْبِيَآءَ عَلَيْهِمُ السَّلاَمُ كَانُوا إِذَا أَقَامُوا أَوْصِيَآءَهُمْ فَعَلُوا ذٌلِكَ وَ أَمَرُوا بِهِ

Imam as-Sadiq [Ja'far ibn Muhammad] (peace be upon him) has said, “It is advisable for you (on the day of Ghadir) to become close to Allah, the Most High, through good deeds, fasting, prayers, establishing (and maintaining) family ties and establishing ties between (your) brothers.  The Prophets (peace be upon all of them) did the same thing when they appointed their successors, and also advised them to act similarly.”

Salat in Masjid al-Ghadir

عَنْ أَبِي عَبْدِ اللٌّهِقَالَ: إِنَّهُ تُسْتَحَبُّ الصَّلوٌةُ فِي مَسْجِدِ الْغَدِيرِ لأََنَّ النَّبِيَّأَقَامَ فِيهِ أَمِيرَ الْمُؤْمِنِينَوَ هُوَ مَوْضِعٌ أَظْهَرَ اللٌّهُ عَزَّ وَجَلَّ فِيهِ الْحَقَّ

It has been narrated from Abi 'Abdillah Imam [Ja'far ibn Muhammad as-Sadiq] (peace be upon him) that: “Surely it is recommended to pray inside Masjid al-Ghadir since verily the Prophet (blessings of Allah be upon him and his family) introduced the Commander of the Faithful (peace be upon him) [as the Imam] to the people here and this is the spot in which Allah, the Noble and Grand, made known The Truth.”

Salat on the Day of Ghadir  

عَنْ أَبِي عَبْدِ اللٌّهِقَالَ: وَ مَنْ صَلَّى فِيهِ رَكْعَتَينِ أَيَّ وَقْتٍ ‏َشَآءَ وَ أَفْضَلُهُ قُرْبَ الزَّوَالِ وَ هِيَ السَّاعَةُ الَّتِي أُقِيمَ فِيهَا أَمِيـرُ الْمُؤْمِنِينَبِغَدِيرِ خُمٍّ عَلَماً لِلنَّاسِ وَ ... كَانَ كَمَنْ حَضَرَ ذٌلِكَ الْيَوْمَ...

It has been narrated from Abi 'Abdillah [Imam Ja'far ibn Muhammad as-Sadiq] (peace be upon him) that: “A person who performs a two Rak'at Salat any time he wishes (during the Day of 18th of Dhul Hijjah), though it is best that this (Salat) be performed as close to the time of Zawwal (mid-day when the sun begins its decline; this is when the time for Salatul Zuhr beings) as possible because this is the time at which Amirul Mo'minin (peace be upon him) was appointed at Ghadir Khumm as the flag of the people and … (the reward for this Salat) is as if the person had been present on the Day (of Ghadir Khumm)…”

Fasting on the Day of Ghadir

قَالَ الصَّادِقُ:صِيَامُ يَوْمِ غَدِيرِ خُمٍّ يَعْدِلُ صِيَامُ عُمْرِ الدُّنْيَا لَوْ عَاشَ إِنْسَانٌ ثُمَّ صَامَ مَا عُمِرَتِ الدُّنْيَا لَكَانَ لَهُ ثَوَابَ ذٌلِكَ

It has been narrated from as-Sadiq [Imam Ja'far ibn Muhammad] (peace be upon him) that: “Fasting on the Day of Ghadir is equivalent to fasting the time span of the (existence of the) entire world – meaning that if a person were to live a life of the entire existence of the world and were to fast this whole time, the reward for this fasting would be equivalent to fasting (this one day of Ghadir).”

The Day of Congratulations and Smiling

عَنِ الرِّضَاقَالَ: ... وَ هُوَ يَوْمُ الْتَهْنِئَةِ يُهَنِّئُ بَعْضُكُمْ بَعْضاً، فَإِذَا لقى الْمُؤْمِنُ أَخَاهُ يَقُولُ: أَلْحَمْدُ لِلٌّهِ الَّذِي جَعَلَنَا مِنَ الْمُتَمَسِّكِينَ ‏بِوِلاَيَةِ أَمِيـرِ الْمُؤْمِنِينَ وَ الأَئِمَّةِوَ هُوَ يَوْمُ التَبَسُّمِ فِي وُجُوهِ النَّاسِ‏ مِنْ أَهْلِ الإِيْمَانِ...

 
It has been narrated from al-Ridha ['Ali ibn Musa] (peace be upon him) that: “…and this is a day of congratulations and felicitations in which you should greet and congratulate one another.  When a believer meets another, one should say, ‘All praise belongs to Allah who has made us amongst those who hold firm to the Wilayat of the Commander of the Faithful and the A’immah (prayers be upon all of them); and this is a day of smiling at other people and those of true faith.”
